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.
