BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid crystal cell multiple substrate including a plurality of liquid crystal cells having an injection port, wherein liquid crystal is simultaneously injected into each liquid crystal cell in a liquid crystal injection step. .

[0002]

2. Description of the Related Art In many cases, a liquid crystal display panel is formed on a mother substrate from the viewpoint of productivity, and a liquid crystal cell multiple substrate (stick substrate) is cut out from the mother substrate in units of one column or one row. . Then, the liquid crystal cell is transported to the liquid crystal injecting step in the state of the multiple substrates, and after the liquid crystal is injected into each liquid crystal cell, the individual liquid crystal cell is cut out from the multiple liquid crystal cell substrate. Is done.

As an example, FIG. 3A shows a front view of a liquid crystal cell multiple substrate 10 cut out from a mother substrate, and FIG. 3B shows a low view thereof. The liquid crystal cell multiple substrate 10 includes a plurality of liquid crystal cells 11 formed of a mother substrate (not shown) in a line.

At the time of cutting out from the mother substrate, the injection port of each liquid crystal cell 11 is taken out. In this example, the injection port 11a of each liquid crystal cell 11 is located on the lower side 1 of the liquid crystal cell multiple substrate 10.
0a.

[0005] In the blank portions 10c at both left and right ends of the liquid crystal cell multiple substrate 10, cutting marks M serving as a reference when cutting out each liquid crystal cell 11 from the liquid crystal cell multiple substrate 10 after injecting liquid crystal.
Is provided.

Usually, the cutting mark M is formed on the strip-shaped substrate 1.
The transparent electrode material (for example, ITO) is formed on one of the inner surfaces of the first and second substrates. That is, the cutting mark M is formed simultaneously with the patterning of the transparent electrode on each liquid crystal cell 11.

The size of the cutting mark M is about 0.5 mm square, and is imaged by a CCD camera of an automatic cell cutting device, and the automatic cell cutting device positions the liquid crystal cell multiple substrate 10 with the cutting mark M as a reference. Then, the cutting operation of each liquid crystal cell 11 is started.

[0008]

SUMMARY OF THE INVENTION A liquid crystal cell multiple substrate 10
In the margin 10c, the cutting mark M is
Although arranged on the b side, the liquid crystal crawls into the margin 10c due to a capillary phenomenon at the time of liquid crystal injection because the gap between the substrates 12 and 13 is narrow, and may adhere to the cutting mark M.

FIG. 4 shows a state in which the liquid crystal L has adhered to the cutting mark M. The cutting mark M is made of a transparent electrode material. In addition to the fact that it is difficult to read even if the liquid crystal L adheres, CC
The cutting mark M cannot be accurately imaged by the D camera, and a cutting trouble occurs due to poor positioning.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and an object of the present invention is to provide a liquid crystal display device having a liquid crystal cell multi-layer substrate, which has a liquid crystal display even if the liquid crystal crawls into a margin where a cutting mark is formed. The object of the present invention is to provide a liquid crystal cell multiple substrate which does not reach the cutting mark.

[0011]

In order to achieve the above object, the present invention provides a liquid crystal display device in which a plurality of liquid crystal cells are arranged in a line between a pair of strip-shaped substrates, the plurality of liquid crystal cells being arranged so as to be aligned with the lower side of the substrates. A liquid crystal cell multiple substrate, which is disposed and has a cut mark for cutting out a liquid crystal cell made of a transparent electrode material formed on the inner surface of one of the margins of the strip substrate, surrounds the cut mark between the strip substrates. A surrounding frame made of a sealing material extending in the lower side direction of the substrate, and the inside of the surrounding frame is divided into multiple stages by a partition having a communicating hole, and a communicating hole communicating with the atmosphere is also provided in the lowermost compartment. It is characterized by being.

This enclosing frame is applied to one substrate side similarly to the peripheral sealing material constituting each liquid crystal cell and is pressed against the other substrate, but the inside thereof is communicated with the atmosphere by a communication hole. Therefore, there is no puncture during crimping.

It is preferable that the communication holes are arranged on the same straight line so that air in the surrounding frame can be easily released at the time of crimping. In addition, even if the liquid crystal enters the surrounding frame from the communication hole, since the inside of the surrounding frame is divided into multiple stages,
It does not easily reach the cutting mark.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a front view of a liquid crystal cell multiple substrate according to this embodiment, and FIG. 2 is an enlarged view of a main part thereof. Note that the same reference numerals are used for components that may be the same as or the same as those in the conventional example of FIG. 3 described above, and a description thereof will be omitted.

Also in this liquid crystal cell multiple substrate 10 ',
A cutting mark M is formed on the inner surface of the margin 10c at both ends, and an enclosing frame 20 made of a sealing material for preventing adhesion of liquid crystal is provided around the cutting mark M.

In this embodiment, the enclosing frame 20 has a vertically long rectangular shape, and its inside is divided into five sections by four partitions 21, and the cutting mark M is the uppermost section 2.
0a.

A communication hole 22 is formed in each partition 21 so that the insides of the sections 20a to 20e communicate with each other. A communication hole 22 is also formed at the bottom of the surrounding frame 20 that forms the lowermost section 20e. Therefore, all the sections 20a to 20e are in communication with the atmosphere.

The surrounding frame 20 is made of, for example, an epoxy-based thermosetting resin like the peripheral sealing material of the liquid crystal cell 11, and is applied to the inner surface of one substrate and then sandwiched between the other substrate. Since the inside is in communication with the atmosphere through the communication hole 22, the air is not trapped inside and does not puncture. In this embodiment, the communication holes 22 are arranged in a straight line so that air can easily escape.

Because of the surrounding frame 20, the cutting mark M
Is protected from the liquid crystal which crawls into the margin 10c when the liquid crystal is injected. In addition, if the surrounding frame 2 is temporarily
Even if the liquid crystal enters into the area 0, there is almost no possibility that the liquid crystal will enter the uppermost section 20a because the surrounding frame 20 is partitioned in multiple stages.

Therefore, in the cell cutting step after the liquid crystal injection step, the cutting mark M can be clearly imaged by the CCD camera of the automatic cell cutting apparatus, and the accurate positioning of the liquid crystal cell multiple substrate 10 'can be performed. Become.

In the present invention, the shape of the surrounding frame 20 can be changed to, for example, an elliptical shape or a gourd shape. The number of steps in the enclosing frame 20 is arbitrary. In addition, each partition 21
The position of the communication hole 22 may be changed every time.

In the above embodiment, the liquid crystal cell multiple substrate is described as being cut out of the mother substrate. However, the liquid crystal cell multiple substrate is initially configured as a liquid crystal cell multiple substrate without going through the mother substrate manufacturing process. Needless to say, the present invention is applicable.

[0023]

As described above, according to the present invention,
In a liquid crystal cell multiple substrate including a plurality of liquid crystal cells arranged in a row and forming cut marks for cutting out liquid crystal cells in margins at both ends, an enclosing frame surrounding the cut marks is formed with a sealant. The inside of the surrounding frame is divided into multiple stages by a partition having a communicating hole, and a communicating hole communicating with the atmosphere is provided in the lowermost section, thereby puncturing the surrounding frame for preventing the adhesion of the liquid crystal to the cutting mark. It can be formed without any.
