DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a substrate for manufacturing a liquid crystal device and a liquid crystal device.

[0002]

2. Description of the Related Art A liquid crystal element is manufactured using two substrates on which electrodes and the like are formed. After a plurality of cells are integrally formed by laminating two substrates with a gap therebetween via a sealant, the substrate is cut into elongated strips, and then liquid crystal is injected and sealed. Thereafter, the strip substrates are cut to produce individual liquid crystal elements.

[0003]

In order to seal the liquid crystal element, it is necessary that the horn forming the liquid crystal injection hole has the two substrates and the sealing material cut at the same end face. Liquid crystal elements used as optical elements are required to be small.

As a result, the gap between the outer shape of the liquid crystal cell and the outer shape of the application pattern of the sealing material is reduced. Therefore, even if the horn for injecting the liquid crystal is extended to the adjacent cell, it cannot be sufficiently extended.

[0005] After a substrate having a plurality of cells formed by laminating two substrates on which electrodes and the like are formed with a gap therebetween through a sealing material, a process of cutting into a long and thin strip is performed by using a scriber and a breaker. It is divided using.

[0006] In the cutting by folding, the cut surface does not become the same end surface unless the cut surface is sufficiently formed of the sealing material and the horn is not extended. That is, if the sealing material (horn) does not sufficiently cross the cut surface, the sealing material cannot be cut well.

[0007]

Means for Solving the Problems In order to solve the above problems, a base material for manufacturing the liquid crystal element of the present invention has the following constitution.

[0008] Two substrates on which electrodes and the like are formed for manufacturing a liquid crystal element. After the two substrates are bonded together with a gap therebetween via a sealing material, a plurality of cells are integrally formed. After cutting into elongated strips, after injecting and sealing the liquid crystal, the substrate of the strip is cut to inject the liquid crystal in the application pattern of the sealing material, which is a base material for manufacturing a liquid crystal element. The horn portion for extending the horn extends to the adjacent cell, and the application pattern of the sealing material of the adjacent cell is formed so as to be depressed so as to escape the horn.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The basic constitution of the present invention is as follows. Two substrates on which electrodes and the like for manufacturing a liquid crystal element are formed. The two substrates are bonded together with a gap therebetween via a sealant to form a plurality of cells, and then cut into elongated strips. Then, after injecting and sealing the liquid crystal, it is a base material for manufacturing the liquid crystal element by cutting the strip substrate, and a horn portion for injecting the liquid crystal of the application pattern of the sealing material has The present invention provides a base material which extends to an adjacent cell, and is formed such that a coating pattern of a sealing material of the adjacent cell is depressed so as to escape the horn.

[0010] Further, there are two substrates on which electrodes and the like for manufacturing a liquid crystal element are formed, and the two substrates are bonded together with a gap therebetween through a sealing material to integrally form a plurality of cells. It is a base for manufacturing a liquid crystal element by cutting the strip substrate after cutting into a long and thin strip, injecting and sealing the liquid crystal, and a horn for injecting the liquid crystal in the application pattern of the sealing material. Is extended to adjacent cells, and after cutting the base material formed by recessing the application pattern of the sealing material of the adjacent cells so as to escape the horn into an elongated strip, the liquid crystal injection and Another object of the present invention is to provide a liquid crystal element which is manufactured by sealing and cutting the strip substrate.

The present invention will be described below with reference to the drawings. FIG.
FIG. 1 is a conceptual diagram showing an embodiment of the present invention. That is, FIG. 1 illustrates a sealing material application pattern for forming a plurality of cells 2 inside a pair of substrates facing each other with a sealing material therebetween and forming a liquid crystal injection port 3 in a part of the sealing material. FIG. The liquid crystal injection port is formed by a horn 1 in a part of the sealing material.

Scribe position 4 for cutting into strips
Is indicated by a two-dot chain line in the figure. The scribe position 5 where the liquid crystal is cut is indicated by a broken line.

In order to seal the liquid crystal element, it is necessary that the horn for forming the liquid crystal injection hole has the two substrates and the sealing material cut at the same end face. Liquid crystal elements used as optical elements are required to be small. As a result, the gap between the outer shape of the liquid crystal cell and the outer shape of the application pattern of the sealing material is reduced.

Accordingly, it is necessary to extend the horn for injecting the liquid crystal sufficiently to the adjacent cells. Hence,
In the embodiment of the present invention, a pair of horns 1 forming the liquid crystal injection port 3 extend to an adjacent cell. Further, the pattern 6 of the sealing material adjacent to the horn 1 is formed so as to escape the horn 1.

[0015]

As is apparent from the above description, according to the present invention, the horn for forming the liquid crystal injection hole can be cut at the same end face between the two substrates and the sealing material, and the liquid crystal element can be satisfactorily manufactured. Can be sealed. Further, it is possible to provide a base material for easily manufacturing the liquid crystal element.
