Liquid crystal cell
First Claim
1. In a liquid crystal cell having a pair of opposed substrates, a sealing member for sealing and joining peripheral portions of said substrates so as to form an enclosed interior space defined by said sealing member and opposed inner surfaces of said substrates, and an injection hole formed by an opening in a part of said sealing member for injecting a liquid crystal into said interior space under vacuum pressure,the improvement comprising:
- a groove formed in the inner surface of one of said substrates leading from said injection hole into said interior space, which facilitates rapid injection of said liquid crystal into said interior space, wherein said groove has a width of 300 μ
m and a depth of 200 μ
m and a length extending along a corresponding length of one peripheral portion of said substrates.

Abstract
A pair of substrates are opposed to each other and the peripheral portions thereof are sealed by a sealing member. A part of the sealing member is opened so as to constitute a liquid crystal injection hole. A groove for introducing a liquid crystal is provided on the inner surface of at least one of the substrates in such a manner as to lead from the injection hole to the inner surface of the cell.
