  However, in the liquid crystal cell assembly described in Patent Document 1, since nothing is formed on the cutting path of the large substrate, the large substrate is greatly bent by the pressing force from the scribe blade when the large substrate is scribed. As a result, there is a problem that the large substrate and the substrate formed by scribing the large substrate may break.

In recent years, especially with the spread of portable models and two-screen models, large substrates are also becoming thinner, and substrate cracking during scribing has become prominent. This technique has been made to solve the above-described problems, and one object of this technique is to provide a liquid crystal display device capable of suppressing the breakage of the substrate in the scribe process. is there.

As a result, when the large substrate is scribed and divided into individual substrates, a spacer is disposed on at least a part of the cutting path (scribe line) of the large substrate. It is possible to function as a support member for the substrate against the pressing force. Therefore, the large substrate can be prevented from being greatly bent by the pressing force from the scribe blade, and the large substrate and the substrate after cutting can be prevented from cracking.

  The liquid crystal display device according to the first aspect preferably further includes an injection port for injecting the liquid crystal formed by the seal member, and the spacer is provided with at least the injection port in the outer peripheral region of the pair of substrates. Placed in the part. If comprised in this way, since a spacer is arrange | positioned in the part of the inlet which is an area | region where the sealing member between large sized substrates is not formed, between the area | region in which the sealing member between large sized boards is formed, and a large sized board | substrate It is possible to suppress the breakage of the large substrate starting from the boundary portion with the region where the sealing member is not formed (portion portion).

  In the liquid crystal display device according to the first aspect, preferably, the spacer disposed between the pair of substrates is disposed along substantially the entire outer peripheral region of the pair of substrates. With this configuration, when the large substrate is scribed and divided into individual substrates, the spacers are disposed over substantially the entire area along the cutting path (scribe line) of the large substrate.

The first spacer is made of the same layer as the liquid crystal layer thickness adjusting layer, and the second spacer is made of the same layer as the spacing regulating member. If comprised in this way, while being able to form a 1st spacer by the same process as a liquid crystal layer thickness adjustment layer, a 2nd spacer can be formed by the same process as a space | interval regulation member. Accordingly, the number of manufacturing steps can be reduced by the amount that the first spacer and the second spacer need not be separately formed, so that the manufacturing process can be simplified.

  In the configuration in which the spacer includes the first spacer and the second spacer, preferably, the second spacer is formed at least in a portion corresponding to the injection port, and the second spacer extends along the outer peripheral region of the pair of substrates. A plurality are provided at predetermined intervals. If comprised in this way, at the time of a scribe, a liquid crystal can be easily inject | poured from the clearance gap between the 2nd spacers of an injection | pouring port, suppressing that a large sized board | substrate breaks with a 1st spacer and a 2nd spacer.

  In this case, the second spacer is preferably in contact with the other of the pair of substrates. If comprised in this way, since the 1st spacer and the 2nd spacer are arrange | positioned without a gap in the direction where a board | substrate opposes in the area | region (portion part of an injection port) in which the sealing member between large sized boards is not formed, it cut | disconnects at the time of a scribe. The liquid crystal can be easily discharged from the gap between the second spacers by the plurality of second spacers provided at predetermined intervals in a direction orthogonal to the direction in which the substrates face each other at the injection port while reliably supporting the large substrate to be formed. Can be injected.

  In the configuration in which the spacer includes the first spacer and the second spacer, it is preferable that the second spacer is formed at least in a portion corresponding to the injection port, and the second spacer is provided in substantially the entire region on the first spacer. It has been. If comprised in this way, since the area | region which supports a large sized substrate at the time of a scribe increases by the part which formed the 2nd spacer in the substantially whole region on the surface of the 1st spacer, it can suppress that a crack generate | occur | produces in a board | substrate. .

  In this case, preferably, a predetermined gap is provided between the second spacer and the other of the pair of substrates. If comprised in this way, a liquid crystal can be inject | poured from the clearance gap between a 2nd spacer and a board | substrate, suppressing that a large sized board | substrate breaks with a 1st spacer and a 2nd spacer.

FIG. 8 is a diagram for explaining a manufacturing process of the display panel of the liquid crystal display device according to the first embodiment of the present technology . Next, with reference to FIGS. 2, 5, and 8, a manufacturing process of the display panel 100 of the liquid crystal display device according to the first embodiment of the present technology will be described.

First, as shown in FIG. 5, the seal member 3 is applied between large substrates 200 on which a plurality of portions to be the display panel 100 of the liquid crystal display device according to the present technology are formed. The seal member 3 is formed on the counter substrate 2. Further, the seal members 3 are applied in a matrix so as to be connected to each row in a plan view. Then, a pair of substrates is attached.

  Next, as shown in FIG. 8, the pair of substrates bonded together is cut along cutting paths (scribe lines) C1-C1, C2-C2, and C3-C3 by a scribing process. Here, in the scribing step, the first spacer 5a and the second spacer 5b function as support members that support the large substrate 200 on the scribe line. Then, the first spacer 5a and the second spacer 5b arranged on the cutting path of the large substrate 200 are also cut by this scribing process. Thereby, the cut-out display panel 100 has the shape of FIG.

  Then, the liquid crystal 4 is injected from the injection port 3a by a vacuum injection method. In this case, in the first embodiment, since the second spacer 5b is disposed with a predetermined gap in the horizontal direction, the liquid crystal 4 can be injected from the horizontal gap between the second spacers. It is. Further, at the time of injecting the liquid crystal 4 by the vacuum injection method, the array substrate 1 side and the counter substrate 2 side at the injection port 3a bend in the opening direction due to the pressure by the injection of the liquid crystal 4. Specifically, it bends so that the distance between the array substrate 1 side and the counter substrate 2 side becomes larger by about 3 μm or more and about 5 μm or less than usual. As a result, a gap is formed in the vertical direction between the second spacer 5b formed on the counter substrate 2 side and the array substrate 1, so that the implantation can be easily performed. Thereafter, the inlet 3a is sealed with a sealing material (not shown).

  Thus, a plurality of display panels 100 having a predetermined size are formed.

  In the first embodiment, as described above, the large substrate 200 is scribed and divided into the individual display panels 100 by arranging the spacers 5 on the surface of the counter substrate 2 along the cutting path of the large substrate 200. In this case, the spacer 5 can be used as a support member for the large substrate 200 against the pressing force from the scribe blade. Therefore, since it is possible to suppress the large substrate 200 from being greatly bent by the pressing force from the scribe blade, it is possible to suppress the breakage of the large substrate 200 and the substrate after cutting (the array substrate 1 and the counter substrate 2). it can.

  Further, in the first embodiment, by arranging the spacer 5 in a portion where the injection port 3a is provided in the outer peripheral region between the array substrate 1 and the counter substrate 2 (portion where the seal member 3 is not provided), It is possible to prevent the large substrate 200 from cracking from the boundary portion between the region where the seal member 3 of the large substrate 200 is formed and the region where the seal member 3 between the large substrates 200 is not formed.

  In the first embodiment, the spacers 5 are arranged along substantially the entire outer peripheral region of the counter substrate 2, thereby causing the spacers 5 to function as support members in substantially the entire cutting path of the large substrate 200. Therefore, the breakage of the large substrate 200 can be more reliably suppressed.

  In the first embodiment, the spacer 5 is constituted by the first spacer 5a provided on the counter substrate 2 and the second spacer 5b provided on the first spacer 5a, whereby the first spacer 5a is formed. The pressing force from the scribe blade can be easily supported by the two spacers, i.e., the second spacer 5b.

  In the first embodiment, the first spacer 5a is formed by the same process as the topcoat layer 22, and the second spacer 5b is formed by the same process as the photospacer 30. Since the second spacer 5b need not be separately formed, the number of manufacturing steps can be reduced. Therefore, the manufacturing process can be simplified.

  In the first embodiment, a plurality of second spacers 5b are provided at predetermined intervals along the outer peripheral region of the counter substrate 2, thereby supporting the large substrate 200 together with the first spacers 5a during scribing. When the liquid crystal 4 is injected, the liquid crystal 4 can be easily injected from the gap between the second spacers 5b of the injection port 3a.

  In the first embodiment, the sealing member 3 between the large substrate 200 is not formed between the first spacer 5a and the second spacer 5b by configuring the second spacer 5b to contact the array substrate 1. Since the substrate is disposed in the region facing the region without a gap, the large substrate 200 is reliably supported during the scribing process, and is provided at a predetermined interval in the direction orthogonal to the substrate facing direction at the injection port 3a. The liquid crystal 4 can be easily injected from the gaps between the plurality of second spacers 5b.

  In the second embodiment, as described above, the second spacers 5c are provided in substantially the entire region on the surface of the first spacer 5a, so that a plurality of the second spacers 5c are arranged with a predetermined interval. Since the region for supporting the large substrate 200 during scribing increases, the large substrate 200 can be easily prevented from breaking.

  In the second embodiment, by providing the gap L3 having a predetermined size between the second spacer 5c and the array substrate 1, the large substrate 200 is broken by the first spacer 5a and the second spacer 5c. The liquid crystal 4 can be easily injected from the gap between the second spacer 5c and the array substrate 1 while being suppressed.

The liquid crystal 4 can be injected from the gap between the spacers 5d, and the length is larger than that of the second spacer 5b of the first embodiment, so that the function as a support member for the large substrate 200 with respect to the scribe blade is improved. Can do. However, as for the injection of the liquid crystal 4, it becomes difficult to inject the liquid crystal 4 as compared with the first embodiment because the interval is narrowed. That is, by adjusting the length of the second spacer 5d, the ease of injecting the liquid crystal 4 and the effectiveness as a support member can be adjusted.

  The remaining effects of the third embodiment are similar to those of the aforementioned first embodiment.
