Definitions
- the present invention relates to a curable resin composition. Specifically, the present invention relates to a sealant that seals liquid or liquid crystal. More specifically, the present invention relates to a liquid crystal dropping method sealing agent for sealing a polymerizable liquid crystal composition and a liquid crystal display device using the same.
- seal liquids or liquid crystals are used in liquid crystal display elements, dye-sensitized solar cells, organic EL elements, and the like.
- a liquid crystal material sealant for liquid crystal display elements as an organic solvent electrolyte such as acetonitrile or propylene carbonate for dye-sensitized solar cells, or as an ionic liquid sealant, for organic EL elements, It is used as a dam material for sealing a liquid sealant in solid sealing.
- Conventional sealants (sealants) come into contact with liquid or liquid crystal in an uncured state, so that the resin components of the sealant are eluted and contaminated, thereby reducing the performance and reliability of the device. There is a problem. Moreover, there exists a problem that a sealing agent becomes weak by elution and it becomes easy to break. Thus, there is a need for a sealant that has low elution to liquid or liquid crystal.
- a liquid crystal dropping method is mainly used as a manufacturing method of the liquid crystal display element from the conventional vacuum injection method for the purpose of shortening the manufacturing process.
- a display element frame is dispensed on a substrate with electrodes by a sealant, and after the liquid crystal is dropped into the drawing frame, the other substrate with electrodes is bonded under vacuum.
- it is a method of manufacturing a liquid crystal display element by irradiating the seal portion with ultraviolet rays to perform temporary curing, and then performing main curing by heating that combines liquid crystal annealing and thermal curing.
- this construction method by adopting two-stage curing by photocuring and thermal curing, the curing time can be shortened and the manufacturing process of the liquid crystal display element can be shortened.
- Liquid crystal panels display as much information as possible on one screen, and therefore tend to have higher definition and higher speed. Furthermore, in recent years, as many liquid crystal panels as possible are cut out from a single glass substrate (mother glass). Accordingly, the material for sealing the liquid crystal has been applied on the black matrix in the substrate having the color filter, and has been applied over the TFT wiring in the counter substrate (TFT substrate). . Therefore, when UV curing is performed, a shadow is generated that is not irradiated to the sealant even if UV is irradiated from either the color filter or the TFT substrate. If the sealant component is uncured at this shadow, the sealant component is thermally cured.
- Liquid crystal compounds having an alkenyl group having a low rotational viscosity coefficient are often blended in nematic liquid crystal materials for TFTs such as TN, VA, and IPS-LCD modes in order to increase the response speed for moving images.
- TFTs such as TN, VA, and IPS-LCD modes
- the photoradical initiator migrates from the sealant to the liquid crystal, thereby causing photodegradation of the alkenyl group.
- Patent Documents 1 to 7 disclose liquid crystal sealing agents using a photo radical initiator having an oxime ester structure.
- the photoradical initiator having a conventional oxime ester structure has insufficient sensitivity, the curing of the sealing agent is weak, the resin component and the initiator itself are eluted in the liquid crystal composition, and the electrical characteristics are deteriorated.
- Even in a highly sensitive oxime ester compound there is a problem in that the decomposition product of the initiator is eluted in the liquid crystal composition and the electrical characteristics are deteriorated.
- the object of the present invention is characterized by two-stage curing of photocuring and thermal curing, a curable resin composition having low contamination and high adhesive strength when in contact with a liquid or liquid crystal, particularly TFT wiring during photocuring.
- a curable resin composition that can be sufficiently photocured even in a shadowed portion (shadow portion) by a black matrix or the like, a sealing agent using the same, a sealing agent for liquid crystal dropping method, and a liquid crystal display element are provided. There is.

Abstract
Description
更に近年では、一枚のガラス基板(マザーガラス)から出来るだけ多くの液晶パネルを切り出す設計がなされている。これに伴い、液晶を封止する材料は、カラーフィルターを有する基板においてはブラックマトリクス上に塗工され、対向基板(TFT基板)においてはTFT配線上に懸かって塗工されるようになってきた。よって、UV硬化時にカラーフィルター、TFT基板どちらの面からUV照射してもシール剤に照射されない影部が生じ、この影部にてシール剤成分が未硬化であると、シール剤成分が熱硬化時に液晶へ染み出すためシール周辺部の表示特性を低下させてしまうという問題があった。
このため、上記影部の出来るだけ深部まで光硬化でき、液晶への溶出物が少ない光ラジカル開始剤及びシール剤が求められてきた。
