Abstract

A sealing structure of a liquid crystal injection holes in a liquid crystal display device, capable of injecting the liquid crystal from a plurality of liquid crystal injection holes into the inside of a liquid crystal cell enclosed by a sealant. The sealing structure of the liquid crystal injection holes is constructed so that each liquid crystal injection holes is linked by a drain of a sealant one to another, and the sealant has an opening portion which connects the inside of the cell with the outside, thus, making it possible to seal all the injection holes by filling the aforementioned drain with the sealing agent which is injected from one of the injection holes.

Dependent claims

A sealing structure of liquid crystal injection holes in a liquid crystal display device, comprising:

a plurality of liquid crystal injection holes formed by printing a sealant on a substrate for injecting a liquid crystal into a liquid crystal cell inside enclosed by the sealant;
a drain formed by printing the sealant on the substrate, by which a plurality of said liquid crystal injection holes communicate with each other;
at least one opening portion formed by printing the sealant on the substrate, by which said drain communicates with said cell inside, said opening portion communicating with a plurality of said injection holes by said drain;
and
a sealing agent injected from one of said injection holes after said injecting of the liquid crystal for sealing a plurality of said injection holes and said drain.
