Abstract

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cell manufacturing method of a liquid crystal display device and to a method of bonding two substrates constituting a cell of a liquid crystal display device to each other.

Conventionally, two sheets of substrates are bonded together by patterning a seal adhesive on a substrate by screen printing. In the process of patterning the seal adhesive on the substrate, the screen mesh is subjected to a constant pressure by a squeegee, so that the seal adhesive is uniformly printed. However, there is a problem in that the pixel portion of the liquid crystal display device is contaminated and pixel defects are generated to lower display quality.

In order to solve this problem, in the present invention, the dummy yarn pattern is first formed before the yarn pattern is formed so that the dummy failure turn can support the screen mesh. Therefore, the pressure applied to the screen mesh is dispersed and the screen mesh is prevented from being stretched, so that a certain seal pattern can be formed and the deformation of the shape of the seal pattern can be prevented, and the screen mesh and the substrate are in contact with each other. This prevents contamination of the pixel portion and pixel defects, thereby improving the display quality.

Claims (13)

A cell of a liquid crystal display device comprising a step of forming a seal pattern on at least one of the substrates in order to bond two substrates of the liquid crystal display device to a liquid crystal display device in which one or more cells are formed on one substrate. A method of manufacturing a cell of a liquid crystal display device, characterized by further comprising a step of forming a dummy yarn pattern. The method of claim 1, wherein the dummy seal pattern is formed to have at least one dummy seal line. The cell manufacturing method of a liquid crystal display device according to claim 1, wherein the dummy yarn pattern is constituted by using an ultraviolet curing agent. The method of claim 1, wherein the dummy yarn pattern is formed to have a height of 100 µm or less. The method of claim 1, wherein the seal pattern is formed after the dummy seal pattern is formed. The method of claim 1, wherein the dummy seal pattern is formed in a non-contact manner. 7. The cell manufacturing method of a liquid crystal display device according to claim 1 or 6, wherein the dummy yarn pattern is formed by using a distribution type device. The method of claim 1, wherein the dummy yarn pattern has an open hole formed on the same side or opposite side as the injection hole formed in the yarn pattern. The method of manufacturing a cell of a liquid crystal display device according to claim 1, wherein the seal pattern comprises a sub seal and a main seal. 10. The method of claim 9, wherein an open is formed in the sub-chamber. 10. The method of claim 9, wherein the sub-chamber and the main-chamber are formed on both sides of the dummy yarn pattern. 10. The method of claim 9, wherein an interval between the sub-chamber and the dummy yarn pattern and an interval between the main yarn and the dummy yarn pattern are equal intervals. 10. The method of claim 9, wherein the sub-chamber and the dummy yarn pattern are removed by cutting after adhering the two substrates.
