Among them, 'the current MVA and IPS driving methods have been widely 97104582 6 200903109. The team has the following unique questions. § · The refractive index anisotropy of the crystal unit or polarizing plate By: : 角依: The problem of sub-sense means that the liquid crystal is installed from the front and the oblique direction: :来=图=The hue and contrast will change. With the emphasis on the importance of the increase - the increase: the screen, the problem of the characteristics of this perspective is to improve the dependence of such perspective, so far technical. As a representative method, there is a method of using a retardation film. This method is as shown in Fig. 8, and the film 103 having a predetermined optical property is disposed between the liquid crystal cell 101 and the polarizing plate and 102B, which deteriorates the dependency of the viewing angle. This method can improve the above-described problem of viewing angle dependence only by incorporating the phase film 103 into the liquid crystal display device. Therefore, it is widely used as a method for easily obtaining a liquid crystal display device having excellent visibility. C is a conventional retardation film having a configuration in which an alignment layer 42 is provided on any transparent substrate 41 as shown in FIG. 9, and a phase difference layer having liquid crystal molecules is formed on the alignment layer 42. 43.

As such a (four)-difference film, for example, Patent Document 1 or Patent Document 2 discloses that a phase difference layer (a phase difference layer exhibiting birefringence) having a cholesterol-like regular molecular structure is formed on a substrate having an alignment layer. Phase difference film. Further, Patent Document '3 discloses a phase difference film in which a phase difference layer (a phase difference layer exhibiting birefringence) containing a disk-shaped compound 97104582 7 200903109 is formed on a substrate having an alignment layer. However, the above-mentioned retardation layer having a biliary regular molecular structure has a problem that it is difficult to exhibit uniform optical characteristics. Here, the method of improving the viewing angle dependence using the above retardation film is useful in that the refractive index difference of the retardation layer can be designed by the phase difference (four) generated by the liquid crystal cell of the liquid crystal display device. The directionality greatly improves the viewing angle dependency of the liquid crystal display device. However, the above-mentioned conventional phase difference thin film must have the above-mentioned alignment layer for aligning the liquid crystal molecules, so that the adhesion between the alignment layer and the phase difference is in order to solve the problem, and the present inventors have provided The retardation layer having the following configuration: a retardation layer is directly formed on the substrate without using the alignment layer (Patent Document 4). Such a retardation film which does not use an alignment layer has an advantage that it can be formed by a simple process and contributes to a reduction in thickness of a liquid crystal display device produced by using the retardation film 1, and therefore has a phase excellent in functionality.

Thus, according to the present invention, a phase difference layer transfer sheet which can produce a retardation film which does not use the alignment layer of 97104582 200903109 can be obtained using any substrate. The phase difference layer transfer sheet of the present invention has at least a release support and a retardation layer for transfer, and may have any other configuration as needed. Hereinafter, each configuration used in the present invention will be described in order. 1. Phase difference layer for transfer First, the phase difference layer for transfer used in the present invention will be described. The phase difference layer for transfer used in the present invention is detachably formed on a release support to be described later, and can be formed by transferring from the release support to another arbitrary substrate to form a phase difference. Floor. Further, the phase difference layer for transfer used in the present invention has a property of being optically negative W. Further, the phase difference layer for transfer used in the present invention is characterized by comprising a polymer of a rod-like compound and the above polyfunctional polymerizable material. Hereinafter, such a retardation layer for transfer will be described in detail. (1) Polyfunctional polymerizable material First, the polyfunctional polymerizable material used in the present invention will be described. The polyfunctional polymerizable material used in the present invention has a structure in which a plurality of polymerizable functional groups are bonded via a spacer, and has a property of facilitating alignment of a rod-like compound to be described later to impart a phase difference layer for transfer. As a property of an optical negative C plate. Further, the polyfunctional polymerizable material used in the present invention is present as a polymer obtained by polymerization via a polymerizable functional group in the retardation layer for transfer. The polyfunctional polymerizable material used in the present invention has a structure in which a plurality of polymerizable functional groups are bonded via a spacer, and can contribute to the discharge of a rod-like compound described later to a phase difference for transfer. The layer is not particularly limited to a polymerizable material as the property of the optically negative c-plate of 97104582 15 200903109, and may be bonded at both ends of the above-mentioned spacer portion! The base bifunctional polymerizable material may alternatively be a polyfunctional polymer having two or more plural polymerizable functional groups in the above (four) =: a polymerizable functional group as long as it can be transferred The polymerization using the phase energy polymerizable material is not particularly limited: η for the phase difference layer produced by using the phase difference layer transfer sheet of the present invention: any polymerization property is used by the formation method of the phase difference layer or the like. Examples of such a polymerizable functional group include an ionizing radiation i which generates a polymerization reaction by irradiation with an ultraviolet ray, a line, or an electron beam; and an 'official base' (especially, the ionizing light is visible light or The ultraviolet ray is referred to as a photopolymerizable functional group, and a thermal polymerizable functional group which reacts by heating. In the present invention, any of the polymerizable functional groups may be preferably used. Among them, it is preferred to use the above-mentioned complex functional group' as a photopolymerizable functional group. The reason for the use of the photopolymerizable functional group as the polymerizable functional group is that the transfer retardation layer to be used is less likely to impair the alignment of the rod-like compound to be described later. (2) The photopolymerizable functional group may, for example, be a radical polymerizable functional group 2 ionic polymerizable functional group. As the above-mentioned radical polymerizable functional group method, at least one ethylenically unsaturated ruthenium group which can undergo addition polymerization can be obtained. More specifically, it may be exemplified by a vinyl group or an acrylate group (including an acrylonitrile group, a methacryl fluorenyl group, a 97104582 16 200903109 acryloxy group, a methyl propyl sulfoxide group). )Wait. On the other hand, examples of the cationically polymerizable functional group include an epoxy group and the like. Further, the polymerizable functional groups used in the present invention may be only two or more. — Next, a description will be given of a portion where a plurality of such polymerizable functional groups are bonded. The spacer used in the present invention is capable of bonding the above-mentioned polymerizable functional groups at a predetermined distance, and can contribute to arranging the rod-like compounds described later to impart optical negativeity to the phase difference layer for transfer. The nature of the c board's county has no special appointments. Among them, in the present invention, it is preferred to use a tobacco chain as the spacer. The reason for this is that the hydrocarbon chain can arbitrarily adjust the distance at which a plurality of polymerizable functional groups are bonded by changing the carbon number. The hydrocarbon chain used in the present invention may be a saturated hydrocarbon chain such as an alkyl group which does not contain an unsaturated bond, or may be an unsaturated hydrocarbon chain containing an unsaturated bond such as a double bond or a triple bond. Further, it may be a linear hydrocarbon chain which does not contain a branch, or may be a branched hydrocarbon chain which has a branch. Further, any functional group and atomic group can be bonded. The number of carbon atoms constituting the hydrocarbon chain used in the present invention is such that the polymerizable functional group can be bonded to a predetermined distance, and the rod-like compound described later can be arranged to be used for transfer. The retardation layer is not particularly limited as long as it imparts properties to the optical negative c-plate. The number of slaves can be arbitrarily adjusted according to the type of the rod-like compound to be described later, and in the present invention, it is preferably in the range of 3 to 15 carbon atoms, particularly preferably 8 to 1 Torr. Specific examples of the polyfunctional polymerizable material used in the present invention include, for example, 1,9-nonanediol diacrylate. 97104582 17 200903109 Further, the polyfunctional polymerizable material used in the present invention may be used alone or in combination of two or more. The content of the polymer of the polyfunctional polymerizable material contained in the retardation layer for transfer of the present invention is not particularly limited as long as it is within the range of the phase difference layer for transfer. The above content may be appropriately determined depending on the type and content of the rod-like compound to be described later. In the present invention, the content of the polymer of the polyfunctional polymerizable material in the retardation layer for transfer is preferably in the range of 10% by mass to 60% by mass based on the mass percentage of the solid content. It is particularly good for the range of 2% by weight to 55% by mass, more preferably 30% by mass to 4% by mass inside the dad. This is because if the content of the above polyfunctional polymerizable material is too large or too small, it may be difficult to impart a desired optical property to the transfer retardation layer. (2) Rod-shaped compound Next, the rod-like compound used in the present invention will be described. The compound of the (4) used in the present invention has a function of: arranging in the retardation layer for transfer, thereby making the transfer >

In addition, the above-mentioned "random horizontal alignment" means an arrangement pattern having the following three characteristics: The arrangement direction of the rod-shaped compound of the phase difference layer t for transfer is parallel to the phase difference layer of the rotation (four) The front and back faces (the faces parallel to the lamp plane) are irregular; the second, the phase difference layer for transfer, and the domain formed by the rod-shaped compound are smaller than the wavelength of the visible light region; In the retardation layer for transfer, the rod-shaped compound is substantially accommodated in one plane (plane parallel to the plane of the lamp) parallel to the front and back surfaces of the phase difference layer for transfer, and is substantially not in the thickness direction (z direction) ) Alignment in a prominent way. Furthermore, here, the meaning of "substantially contained" and "substantially not prominent" will be supplemented. In general, the rod-shaped molecules themselves are not only linear and have a stereostructure, and the functions are based on the protrusion in the side chain direction and the bending of the main chain of the molecule. Therefore, in geometry, strictly speaking, 97104582 26 200903109 In most cases, the rod-shaped molecules as a whole cannot exist in only one plane. However, the molecular weight of the φ-wide rod-like compound is prominent (or the effect of the partial large part (for example, the difference between the thickness direction direction and the theoretical value of the case where the molecule is completely present in one plane t) is practical. In the case of negligible privateness (usually less than about 10 nm), the rod-shaped molecules are regarded as "realized in a plane" and "substantially not protruding in the thickness direction". The rod-like compound contained in the retardation layer for transfer of the invention is not particularly limited as long as it imparts desired optical characteristics to the retardation layer for transfer. The present invention: two == The polyfunctional polymerizable rod-like compound contained in the layer is 100 parts by weight to 240 parts by weight, more preferably 13 parts by weight to 220 parts by weight, and most preferably (5) parts by weight to 2 parts by weight. Further, (3) In the retardation layer for transfer of any material, in addition to the above-mentioned rod-like compound and the polymer of the poly-anthracene: the sound can be contained in any other material. 'Can be used according to the phase difference of the present invention The two-dimensional layer of the transfer sheet imparts a desired function. As the second aspect of the present invention: =, for example, a photopolymerization initiator, polymerization inhibition, a chiral agent, a decane coupling agent, etc. The other compounds used in the present invention are usually used as a sub-film, and thus detailed description thereof will be omitted. 97104582 27 200903109 (4) The retardation layer for transfer is as described above, and the transfer used in the present invention is used. The printing retardation layer is formed in a peelable manner on a release-retaining support to be described later. Here, the term "removable" means that the adhesive force can be peeled off without causing damage to each other. The phase difference layer for transfer is adhered to a mold release support to be described later. Therefore, the phase difference layer for transfer used in the present invention is formed on the mold release support, and the film can be removed from the above. The adhesiveness of the mold-peeling layer is not particularly limited as long as it does not cause damage to each other.

The substrate used in the present invention supports the phase difference layer described above. In the present invention, since the retardation layer having the above configuration is used, any substrate can be used depending on the use of the retardation film or the like. Hereinafter, the substrate used in the present invention will be described in detail. The transparency of the substrate produced by the present invention may be arbitrarily determined according to the transparency required for the retardation film of the present invention. Usually, the transmittance in the visible light region is preferably 80% or more, more preferably 9 Å. %the above. If the transmittance is low, the retardation film of the present invention sometimes causes the haze to be larger than a desired value. Here, the transmittance of the substrate can be measured by JIS ^加丨 (Test method for total light transmittance of plastic_transparent material). As long as the substrate used in this month has the above transparency, a flexible material having flexibility or a rigid material having no flexibility can be used. Among them, in the present invention, it is preferred to use a flexible material. The reason for this is that the manufacturing step of the phase difference thin film of the present invention can be a roll-to-roll process by using a flexible material. The flexible material may, for example, be an acrylic resin such as a cellulose derivative, a cycloolefin polymer or a polymethyl methacrylate, a polyethylene terephthalate or a polybutylene terephthalate. Polyethylene naphthalene acetate, polyester such as polyacrylate, polyvinyl alcohol, polyimine, polyfluorene, polyether sulfone, amorphous polyolefin, modified acrylic polymer, polystyrene, ring Oxygen resin, 97104582 37 200903109 A substrate composed of polycarbonate. Among them, in the present invention, it is preferred to use a substrate composed of a cellulose derivative or a cycloolefin polymer. The cellulose isomer is particularly excellent in optical isotropic properties, so that a phase difference film excellent in optical characteristics can be obtained. X, the cycloaliphatic hydrocarbon compound has high durability in a high-temperature and high-humidity environment, and thus a retardation film excellent in durability of optical characteristics can be obtained. As the cellulose derivative 4 used in the present invention, cellulose vinegar is preferably used, and among the cellulose vines, lysine cellulose is preferred. And the reason is that bismuth cellulose is widely used in industry, so it is advantageous from the viewpoint of obtaining the susceptibility. "Chemical cellulose, preferably a lower fatty acid having a carbon number of 2 to 4, as such a lower fatty acid vinegar, for example, may be a single lower fatty acid vinegar such as cellulose acetate, and may also be, for example, acetic acid. Cellulose or cellulose acetate propionate contains a plurality of fatty acid vinegars. ^In the middle, upper and lower fatty acid vinegar, it is especially preferable to use cellulose acetate (acetate Η: cellulose acetate in 'the best use of average acetamidine The degree of conversion is 57·5~62·5% (substitution degree·· U~3· bis cellulose acetate. Here, t-. . . . ^ 明 醯 degree, means the mass per unit = B The degree of sulphurization can be produced by the acetaminophen of the "Cafic Cellulose Test Method". In addition, the composition of the cellulose triacetate thin:: and 5 different, can be included in the film. It can be determined by the method of brewing 3 = acid cellulose B. (10) After the removal of the specific impurities, by the above, as the present invention, the one having the cyclic olefin (ring_) is included; = 97104582 38 200903109 is not particularly limited. As such a monomer, a ring olefin can be exemplified, for example, a shaker Or more than a olefinic monomer, etc. Further, as the present invention, the use of a cycloolefin polymer can be preferably used in the present invention. Any one of (3) c. The single ft μ & δ δ of the hydrocarbon may be a homopolymer or a copolymer containing the above-mentioned ring, and the cycloolefin f and water absorption ratio used in the present invention are! The mass% is below the range of 23% of the mass% of the product. ^ Because the two cars are in the range of °, 1% by mass to 〇.7 The character m is: (4) ΓΓ phase difference by using the cyclic olefins It is more difficult for the film to change the change in the properties or the size caused by the water absorption. The above-mentioned saturated water absorption rate is determined by measuring the weight gain after sub-crushing in water at 23 ° C for one week in accordance with ASTM D570. The cycloolefin polymer to be used is preferably in the range of 100 C to 200 ° C, and more preferably in the range of 1 〇〇〇 c to 18 〇〇 c. 〇〇 ° C ~ 150 〇 c. The reason is: by / / glass transition temperature is within the above range, can be used The phase difference film of the present invention is more excellent in the heat resistance and the medicinal properties. The substrate composed of the cycloolefin polymer used in the present invention is, for example, a product manufactured by Ticona Co., Ltd., manufactured by Topas and JSR. Art〇n, ZE0N0R manufactured by Zeon Corporation of Japan, ZE0NEX manufactured by Zeon, Japan, ApEL manufactured by Mitsui Chemicals Co., Ltd., or those obtained by extending the substrate, etc. As a rigid material lacking flexibility Examples thereof include 97104582 39 200903109 glass bottles such as soda glass, potassium glass, and borosilicate glass. The thickness of the substrate used in the present invention is not particularly limited as long as it is necessary for the use of the phase difference film or the like. The present invention is not limited to the above-mentioned flexible:: (4) is within the range of "..." Among them, the reason is that if the thickness of the substrate is thinner than: / Sometimes the phase difference of the present invention cannot be obtained by my support. Moreover, the reason is that The phase difference of the invention is thinner than that of the upper 14th circumference, or the wear of the cutting blade becomes faster. „The situation is that the thickness of the material is about 05mm~5mm: = The composition of the substrate is not limited to The brothers of the layer have the composition of a plurality of layers. In the case where there are a plurality of layers, a layer having the same composition may be laminated, or a plurality of layers having different compositions may be laminated. Moreover, the attribution of the present invention can be extended. The reason for this is that the substrate and the phase-contact property can be improved by a substrate which is subjected to elongation treatment. Here, the above-described stretching treatment is not particularly limited, and any shirt may be used depending on the material constituting the substrate or the like. As such extension processing, a uniaxial stretching process and a biaxial stretching process are exemplified. Further, the form of the substrate used in the present invention may be a sheet having a fixed size or may be an elongated film having a fixed length. In the case where the substrate is the above-mentioned elongated film, it is preferably in the form of a roll which is generally used in the industry. 3. Ren Si composition 97104582 40 200903109 The retardation film of the present invention is brought to φ and any other constitution is used as needed. , the purpose of: the difference layer and the substrate, can be formed, can be used without any damage to the phase difference film of the invention used in the invention::: the inner basin can be used arbitrarily Jia (4) is a self-contained constitutive person, and can be used as the above-mentioned substrate and the above-mentioned phase difference layer: the function of the adhesion between the two. By using such adhesion = the phase difference layer of the retardation film of the present invention can be made to have a different adhesion to the substrate. Furthermore, the adhesive used in the present invention is formed by laminating one of the layers of the adhesive (four), that is, the release-preventing support/transfer with the phase difference layer/adhesive layer, and is also formed in advance in the transfer. Alternatively, the adhesive layer may be formed on the substrate of the phase difference thin layer without being disposed on the transfer layer side (the transfer body side, and the thickness of the adhesive layer is usually i Am~2〇Am). The following is a detailed description of the adhesive layer. t. As the adhesive layer used in the present invention, there is no particular adhesive layer as long as it contains an adhesive resin and can adhere the phase difference layer to the substrate with a desired adhesive force. Therefore, the type of the above-mentioned adhesive resin is appropriately selected depending on the type of the base material and the retardation layer. Examples of the adhesive resin used in the present invention include polyethylene, polypropylene, and polyisobutylene. Polyolefins such as polystyrene, ethylene-propylene rubber, ethylene-vinyl acetate copolymer, ethylene-acrylic acid copolymer, cellulose derivatives such as ethyl cellulose and cellulose triacetate, poly(indenyl)acrylic acid and Ester Polyvinyl acetate, polyvinyl alcohol, polyvinyl butyral and other polyvinyl acetals, polyacetal, poly 97104582 41 200903109 decylamine, polyimine, nylon, polyester resin, urethane resin Further, the adhesive resin used in the present invention may be used alone or in combination of two or more. The thickness of the adhesive layer used in the present invention may be any type according to the above-mentioned adhesive resin. It is not particularly limited as long as it adheres to the above-mentioned phase layer and the above-mentioned substrate with a desired adhesive force. The adhesive layer used in the present invention has an adhesive force which is adhered to the above by a specific adhesive force. The degree of the substrate and the retardation layer described above is not particularly limited. In the present invention, it is preferable to apply a scotch tape to the grid-like scratch of the phase difference layer as described above. In the peeling test, the number of squares of the phase difference layer peeled off and transferred to the side of the transparent tape is 50 or less, more preferably one or less, or ί is: The evaluation is carried out by the test In this case, the phase difference thin film has the property of being an optical negative C plate, so the phase difference thin body has optical negative The nature of the C plate. Further, the retardation film of the phase of the present invention can be used alone or in combination with other retardation films. Here, M ii α, | pp
