Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a method for manufacturing a liquid crystal panel, and more particularly, to a method for manufacturing a liquid crystal panel using thin glass as a panel substrate.

[0002]

2. Description of the Related Art In general, a liquid crystal panel is attached to a pair of glass substrates via a sealing material formed so as to orbit around a display area, and is sandwiched between the two glass substrates. The liquid crystal is sealed in a region surrounded by the sealant, and the liquid crystal is generally configured. In order to manufacture such a liquid crystal panel, an electrode is formed, an alignment film is applied, and a sealant is printed on a surface of one glass substrate facing the other glass substrate. Further, on the surface of the other glass substrate facing the one glass substrate, formation of a color filter, an electrode, and the like, application of an alignment film, dispersion of spacers, and the like are performed. Then, these glass substrates are transported to a panel bonding apparatus, where the bonding of the two glass substrates, the molding of the cell gap, the main curing of the seal, and the like are performed. Thereafter, after the two glass substrates are cut off, the liquid crystal is sealed in a region sandwiched between the two glass substrates and surrounded by the sealing material, whereby a liquid crystal panel is manufactured.

In recent years, with the miniaturization and weight reduction of portable information devices and the like, the thickness of liquid crystal panels has been increasingly reduced, and the thickness of glass substrates has been reduced to about 0.3 mm. Since such a thin glass substrate (hereinafter, referred to as a thin glass) is easily bent due to its thinness and is difficult to be conveyed and processed, a liquid crystal panel is manufactured by a conveyance process and a bonding as shown in FIGS. And a dividing step.

That is, as shown in FIG. 6A, a thin glass 1A having a relatively large thickness is provided.
And a transport glass plate 2A having substantially the same shape as the above. Then, the thin glass plate 1A and the glass plate 2A for transportation are arranged to face each other, and the two are bonded together with an adhesive 3A interposed between the peripheral portions of the thin glass plate 1A and the peripheral portion thereof. As shown in FIG. 1A, the thin glass 1A and the transfer glass plate 2A are set to have a predetermined interval. In this way, the thin glass 1A is fixed to the glass plate 2A for conveyance by the adhesive 3A, so that the conveyance property and the assembling property are improved, and the conveyance can be performed on the existing conveyance line.

Next, as shown in FIG. 6B, a sealing material 4 is printed on the surface of the thin glass 1A so as to surround the display area (pixel forming area). Then, the thin glass sheet 1A on which the sealing material 4 is printed is set in a bonding apparatus (not shown). FIG. 7 is a plan view showing this state. On the other hand, in the same manner as in the assembled body of the thin glass 1A and the transport glass plate 2A, a thin glass 1B and a transport glass plate 2B bonded together with an adhesive 3B are prepared.
A and B are set in a bonding device (not shown) so that they face each other. Then, as shown in FIG.
The thin glass sheets 1A and 1B are bonded together via the sealing material 4. Prior to this bonding, spacers are appropriately scattered between the thin glass sheets 1A and 1B.

[0006] The thin glass sheets 1A and 1B thus bonded together are subjected to a cell gap molding and then subjected to a full curing treatment of a sealing material. Thereafter, as shown in FIG. 7A, the transfer glass plates 2A, 2B are moved from the thin glass plates 1A, 1B.
Is removed by peeling off the adhesives 3A and 3B. Next, as shown in the figure, along the scribe street surrounding the sealing material 4 on the surface of the thin glass 1A, 1B,
By performing half-cutting (scribed), scribe grooves 5A and 5B having a V-shaped cross section are formed.

[0007] Then, using a cell substrate break machine, for example, scribe grooves 5B of the thin glass 1B in FIG.
A pressure is applied in the direction indicated by the thick arrow to (B), and the thin glass 1A on the opposite side is divided by the scribe grooves 5A. Conversely, in order to divide the thin glass 1B by the scribe grooves 5B, a position corresponding to the scribe grooves 5B on the surface of the thin glass 1B opposite to the surface on which the scribe grooves 5A are formed is pressed. By sequentially cutting the thin plates 1A and 1B in this manner, a liquid crystal cell having a desired size can be manufactured. The liquid crystal cell thus formed is
Liquid crystal is injected into a region sandwiched between the thin glass plates 1A and 1B and surrounded by the sealing material 4 to form a liquid crystal panel.

[0008]

However, in the method of manufacturing a liquid crystal panel described above, the thin glass 1A,
1B, the transfer glass plates 2A, 2B
It is necessary to remove B from the thin glass plates 1A and 1B, and there is a problem that the number of steps is increased. Moreover, the removal operation itself was difficult. That is, the transport glass plates 2A, 2B are combined with the thin glass plates 1A, 1A.
When the sheet glass 1A, 1B is peeled from the sheet glass 1A, 1B, a stress is applied to the sheet glass 1A, 1B to separate the sheet glass 1A, 1B from the sealing material 4, or the sheet glass 1A, 1B is broken. Occurs and the electrodes formed on the thin glass plates 1A and 1B are cracked to cause disconnection. Also, adhesive 3
When a solvent is used to remove A and 3B, there is a problem that the thin glasses 1A and 1B and the sealing material 4 are adversely affected. For this reason, it is necessary to cut the adhesives 3A and 3B at the intermediate portion or to cut and remove the glass plates 2A and 2B for conveyance. In such a case, too, the stress is applied to the thin glass 1A and 1B side. But it was inevitable. Also, in the thin glass sheet 1A and the thin glass sheet 1B having a narrow gap, it is inevitable to form the scribe grooves 5A and 5B on the surface on the opposite side (outside) of the facing surface. As shown in (B), the other thin glass 1B is pressed to press one thin glass 1B.
It is necessary to press the back side of the scribe groove 5A of A.
For this reason, there has been a problem that the pressing jig presses the other thin glass 1B and adversely affects the thin glass 1B. Further, in order to separate the other thin glass 1B by the scribe grooves 5B, it is necessary to press the thin glass 1B from the surface opposite to the surface on which the scribe grooves 5B are formed.
The pressing jig contacts the edge of one of the thin glass plates 1A,
There was a problem of adversely affecting the thin glass 1A.

The problem to be solved by the present invention is to reduce the number of steps while using a transfer glass plate for improving the transfer (flow) property in a transfer line, and to easily and surely cut thin glass. What means should be taken in order to obtain a liquid crystal panel manufacturing method that can be performed?

[0010]

In order to solve the above-mentioned problems, a method of manufacturing a liquid crystal panel according to the present invention comprises a pair of thin glass plates constituting a liquid crystal panel, each of which is opposed to a different glass plate for transportation. A pair of transfer units are created by pasting, and the thin glass plates of the pair of transfer units are bonded to each other via a sealing member so as to face each other, and the thin glass plate is cut along a scheduled cutting line outside the sealing member. A method for manufacturing a liquid crystal panel, comprising: forming a scribe groove in advance on each of the facing surfaces of the thin glass opposed via the sealing material along the planned dividing line; Forming a pair of transport units by forming scribe grooves in advance on the surface of the plate that faces the thin glass along the planned dividing line, After the thin glass sheets are opposed to each other by opposing a feeding unit and bonded together via the sealing material, a surface of the pair of transport units opposite to a surface on which the scribe grooves of the transport glass plates are formed. And pressing the position corresponding to the scribe groove to separate the transfer glass plate and the thin plate glass of each transfer unit at each scribe groove.

[0011] According to such a configuration of the present invention, it is possible to improve the transportability of the thin glass that is difficult to be placed on the transport line, and to facilitate the work of bonding a pair of thin glass. That is, if the transport glass plate that holds the thin glass is transparent, the positioning of the pair of thin glass can be easily performed. In addition, a scribe groove is formed on the opposite surface of the thin glass in advance, and a scribe groove is also formed on the surface of the transfer glass plate facing the thin glass in the same transfer unit in advance. The traveling direction of the vertical crack in the scribe groove of the glass plate for conveyance is the same direction. For this reason, when the thin glass sheets are bonded to each other with a sealant facing each other, the scribe grooves of the transport units to which the thin glass sheets belong are easily broken in directions opposite to each other. Then, by pressing (pressing) a position corresponding to the scribe groove on the surface opposite to the surface on which the scribe groove is formed on the glass plate for conveyance of one of the transfer units, the transfer plate constituting the one transfer unit is formed. The scribe grooves of the glass plate and the thin glass plate are easily broken by the action of being pushed and spread, and the vertical cracks progress. At this time, the scribe grooves of the thin glass and the transfer glass plate of the other transfer unit undergo an action of being narrowed, but the vertical cracks do not easily proceed, so that the separation is unlikely to occur. Thereafter, if pressing is performed at a position corresponding to the scribe groove on the surface opposite to the surface on which the scribe groove of the transfer glass plate of the other transfer unit is formed, the transfer glass plate and the thin glass of the other transfer unit are pressed. Due to the action of expanding the scribe grooves, vertical cracks progress and cause division.

As described above, according to the present invention, it is not necessary to peel off or cut the glass sheet for conveyance from the thin glass sheet after laminating the pair of thin glass sheets, so that generation of particles and the like can be suppressed. In addition, the number of steps can be reduced. In addition, since the directions in which the assembled transport units are easily separated are opposite to each other, no stress is exerted to separate the thin glass sheets constituting the liquid crystal cell, so that adverse effects on the liquid crystal cell can be suppressed.

According to the present invention, the panel can be easily divided by forming the scribe grooves over the mutually parallel sides of the surface of the thin glass sheet and the glass sheet for conveyance. That is, since the scribe groove is formed linearly so as to cross the thin glass and the glass sheet for conveyance,
Since the bending directions of the thin glass sheet and the glass sheet for conveyance due to the pressing become uniform, a uniform dividing plane can be formed.

In the present invention, the scribe grooves may be formed on the surfaces of the thin glass sheet and the glass sheet for conveyance so as to draw a rectangle surrounding the position where the sealant is disposed. According to such a configuration of the present invention, it becomes possible to cut the thin glass and the transport glass plate constituting the transport unit by the scribe groove by one pressing operation. For this reason, when a pair of thin glass sheets are pasted together via a sealing material, two transport units are assembled, but these can be separated by scribe grooves by pressing twice. For this reason, there is an effect of further reducing the number of steps.
In the case where the scribe groove is formed in a rectangular shape as described above, the scribe groove is preferably set to be slightly deeper.

Further, in the present invention, it is preferable that the thin glass sheet and the glass sheet for conveyance, which constitute the conveyance unit, are bonded to each other with an adhesive so as to be separated from each other by a predetermined distance. According to the present invention having such a configuration, it is possible to prevent the transfer glass plate from pressing the peripheral portion of the thin glass when the transfer glass plate is pressed during the dividing operation, which has an adverse effect on the liquid crystal cell. Can be prevented from reaching.

Further, in the present invention, it is preferable that the adhesive is disposed outside the region surrounded by the scribe groove and does not overlap the scribe groove. According to the present invention having such a configuration, it is possible to prevent the separation by the adhesive when the separation is performed by pressing.

Further, in the present invention, it is preferable that the adhesive contains a gap material for defining a distance between the thin glass and the glass sheet for conveyance. According to the present invention having such a configuration, the gap between the thin glass sheet and the glass sheet for conveyance can be defined by the gap material. For this reason, it is possible to suppress the transfer glass from pressing the peripheral edge of the separated transfer glass plate at the time of pressing accompanying the cutting operation.

In the present invention, the thickness of the thin glass is
It is more effective in the case of 0.3 mm or less. That is, a thin glass plate having a plate thickness of 0.3 mm or less easily bends, and the transportability in the transport line is significantly deteriorated. According to the present invention having such a configuration, the transportability is improved, and in the cutting step, This has the effect of improving the handleability of the device.

[0019]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a method for manufacturing a liquid crystal panel according to the present invention will be described in detail based on an embodiment shown in the drawings. The present invention can be applied to various liquid crystal panels such as a passive matrix liquid crystal display device and an active matrix liquid crystal display device.

(First Embodiment) FIGS. 1 to 4 show a first embodiment of the present invention. FIG. 1A is a plan view of the transport unit, and FIG. 1B is a cross-sectional view taken along the line AA of FIG.

First, in the first embodiment, for example, a thin glass 11 is prepared as one of the pair of panel substrates of a liquid crystal panel on which electrodes, alignment films, etc. (not shown) are formed. As shown in FIGS. 1 (A) and 1 (B), the surface S on the side of the thin glass 11 on which the electrode and the alignment film (not shown) are formed is a line (scribe street) near the peripheral edge to be divided. Scribe by scribe along the scribe groove 11A, 1
1A, 11B and 11B are formed so as to be parallel to the four sides of the thin glass 11. That is, as shown in FIG.
The scribe grooves 11A are parallel to each other, and the scribe grooves 11B are also parallel to each other. The scribe grooves 11A and the scribe grooves 11B are formed so as to intersect at the four corners of the thin glass plate 11. Also, as shown in FIG. 1B, these scribe grooves 11A and 11B
The groove has a substantially V-shaped cross section. Here, it is needless to say that the scribe grooves 11A and 11B are set so as to be positioned outside a region which is formed in a later step and is surrounded by the sealing material in a plane.

In the first embodiment, a thin glass plate 11 as a panel substrate on the opposite side and a relatively thick glass plate 12 for transport having a substantially the same shape (rectangular shape) as the thin glass plate 11 are prepared. . In addition, the thickness of the glass plate 12 for conveyance is a thickness which can have a predetermined rigidity and a desired deformability in a conveyance process, a bonding process, and a cutting process when the thin glass 11 is held. The thickness is appropriately set according to the ease of division (pressure break), the thickness and size of the thin glass 11, the cell gap of the liquid crystal panel to be manufactured, and the like. Then, one surface S ′ of the transfer glass plate 12
The scribe grooves 11A, 11A, 11B, 11B of the thin glass 11
Scribe groove 1 so as to be at the same position
2A, 12A, 12B and 12B are formed.

Next, as shown in FIG. 1 (B), the adhesive 13 is applied to the thin glass 11 and the glass plate 12 for transportation so that the scribe grooves of the thin glass 11 and the glass plate 12 of the conveyance glass coincide with each other (ie, they are positioned to overlap each other in a plane). Are stuck so as to form a predetermined interval.
The adhesive 13 may include a gap material so that the thin glass 11 and the glass plate 12 for conveyance can be set at a predetermined interval. Further, the adhesive 13 is formed as shown in FIG.
And (B), as shown in FIG.
A, 11B, and 12B are arranged outside (peripheral side), and are separately arranged and formed so as not to cross the scribe grooves. That is, the scribe groove 11A and the scribe groove 11B, and the scribe groove 12A and the scribe groove 1
At the four corners where 2B intersects, the adhesive 13A is arranged separately so that the adhesive is not arranged at a position directly below the scribe groove. In this way, the thin glass 11 is held by the glass plate 12 for conveyance, and the conveyance unit U1
Is configured.

The method of manufacturing the transport unit U1 including the one thin glass 11 forming the liquid crystal panel has been described above. However, the other thin glass 14 facing and disposed on the one thin glass 11 and forming the liquid crystal panel has been described. 2B, a similar transport unit U2 is fabricated by applying the same fabrication method as shown in FIG. Note that the thin glass 1 in the transport unit U2 is
The scribe grooves 14A, 14A, 14B, and 14B are formed on the surface facing the substrate 1 so that the positional relationship between the scribe grooves 11A, 11A, 11B, and 11B on the thin glass 11 side is the same in the planar or cross-sectional structure. I do. Further, a scribe groove 14A of the thin glass 14 is provided on a surface of the transport glass plate 15 which holds the thin glass 14 with the adhesives 16 and 16A.
The scribe grooves 15A, 15A, 15B, 15B are formed so that the positional relationship is the same as that of 14A, 14B, 14B in a planar or cross-sectional structure. That is, the bonding structure of the thin glass 14 and the glass plate 15 for transfer is exactly the same as the bonding structure of the thin glass 11 and the glass plate 12 for transfer.

Next, the sealing material 1 is applied to the surface of the thin glass 11.
7 is formed by, for example, a printing method, and then the transfer unit U is formed.
1, U2 is conveyed to a bonding apparatus, and alignment is performed. As shown in FIGS. 2A and 2B, bonding of thin glass 11 and thin glass 14, cell gap molding, and full curing of a seal are performed. And so on. Note that FIG.
A dashed line SL shown in (A) indicates a scribe street where a scribe groove is formed.

Thereafter, the transport units U1 and U2 thus bonded are transported to a dividing line (not shown), and are separated by a break machine (not shown). In the dividing method performed here, as shown in FIG. 3, for example, the transport glass plate 12 is placed on the base 18. Then, a position (indicated by a thick arrow in FIG. 3) is applied to the position corresponding to the scribe grooves 15 </ b> A of the glass plate 15 for conveyance. That is, the scribe grooves 15A, 15B are formed on the surface of the glass plate 15 for conveyance opposite to the surface on which the scribe grooves 15A, 15B are formed.
B is pressed to a position where the positional relationship is the same in the planar or cross-sectional structure above and below, so that the scribe grooves 15 </ b> A, 14 </ b> A of the transport glass plate 15 and the thin glass 14.
A is separated by advancing and spreading action of a vertical crack. At this time, the glass sheet 15 for conveyance has no connection with the thin glass 14, so that the thin glass 1
4 can be removed. Thus, the division of the thin glass 14 and the glass sheet 15 for conveyance is completed.

Thereafter, as shown in FIG.
4 is placed on the base 18, and pressure is applied to the position corresponding to the scribe grooves 12 A of the glass plate 12 for conveyance in the same manner. By this pressing, the vertical cracks in the scribe grooves 12A and 11A of the glass sheet 12 for conveyance and the thin glass sheet 11 are pushed apart and cut. As a result, the glass plate 12 for conveyance can be removed because there is no connection portion with the thin glass 11. Thus, the liquid crystal panel (liquid crystal cell) 10 in which the liquid crystal is not sealed as shown in FIG. 4 can be manufactured. After such a dividing step, the liquid crystal panel 10 can be completed by injecting (vacuum injecting) and sealing a liquid crystal material from the opening 17A of the sealing material 17 shown in FIG. .

In the first embodiment, the thin glass 1
Since the transfer units U1 and U2 are formed by adhering the transfer glass plates 1 and 14 to the transfer glass plates 12 and 15, respectively, the rigidity of the transfer glass plates 12 and 15 can be enjoyed.
Moreover, since the thin glass plates 11 and 14 are protected by the glass plates 12 and 15 for transportation, they can be smoothly transported along the transportation (flow) line without being damaged. In addition, since the glass plates 12 and 15 for transportation can be automatically divided and detached by the scribe grooves by being pressed in the dividing step, as in the conventional case, the adhesive is peeled or cut, or the glass plate for transportation is removed. It is possible to avoid work that has a large adverse effect on the thin glass, such as cutting a glass plate, and reduce the number of steps. Furthermore, in this embodiment, since the transport unit directly pressurized by the break machine can be divided, it is possible to prevent an unnecessary bending load from being applied to the thin glass as in the related art.

Embodiment 2 FIG. 5 is a plan view showing Embodiment 2 of a method for manufacturing a liquid crystal panel according to the present invention. The second embodiment is different from the first embodiment only in the configuration of the scribe groove, and only different portions will be described below. The same parts as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

In the second embodiment, as shown in FIG. 5, scribe grooves 11A formed on a predetermined surface of
11B is formed parallel to the periphery of the thin glass 11 but does not reach the edge of the thin glass 11 in the extending direction. The scribe grooves 11A and 11B are thin glass 1
The scribe grooves 11A and 11B are formed so as not to extend between the two opposing substrate sides, but to form one side of the square inside the outer shape (each substrate side) of the thin glass 11. . Accordingly, the adhesive 13 is formed so as to surround the outside of the square formed by the scribe grooves 11A and 11B. The structure of the transport unit U1 is the same in the transport unit U2. In the second embodiment, with such a configuration, the thin glass sheets 11 and 14 are bonded together with the sealing material 17 interposed therebetween, and cut into pieces at once by scribe grooves forming the respective sides of the square. Therefore, the number of dividing steps may be two. In the second embodiment, it is preferable to set the depth of the scribe groove relatively deep in order to divide the scribe grooves formed along different directions.

The other configuration of the second embodiment is as follows.
The third embodiment is the same as the first embodiment, and the operation and effect are the same as those of the first embodiment.

Although the first and second embodiments have been described above, the present invention is not limited to these, and various changes accompanying the gist of the configuration are possible. For example, in Embodiments 1 and 2 described above, it is only necessary that the glass sheet for conveyance be larger than a thin glass sheet set to a size similar to that of the thin glass sheet. In the above-described first and second embodiments, the thin glass and the glass plate for conveyance are bonded with an adhesive. However, as the adhesive, a sealing material for bonding the thin glass with each other may be used.
