Title:
LIQUID CRYSTAL DISPLAY ELEMENT AND ITS PRODUCTION
Document Type and Number:
Japanese Patent JPH10123537
Kind Code:
A
Abstract:

To obtain a liquid crystal display element which is free from image unevenness defects by peeling of seals for sticking two substrates to each other and with which the aperture ratio of a screen may be increased by using the seals which consist of double structures consisting of an elastic material seal in the inner side.

The elastic material seal 9 on the inner side, the outer seal 10 and liquid crystals 11 are arranged between the two substrates 7 and 8 arranged to face each other while a specified gap is maintained therebetween. The elastic material seal 9 on the inner side adheres to the one substrate 7 alone and is merely into contact with the other substrate 8 and is not adhered and fixed thereto. Then, even if the force by working in later stages acts on the substrates, the upper side of the elastic material seal 9 is freely movable and the force acting over the entire part of the elastic material seal 9 decreases and, therefore, the seal peeling is lessened. The elastic material seal 9 is formed taller than the outer seal 10. A hermetic sealing effect is thus obtd. by the falling and contracting of the elastic material seal 9 at the time of sticking the substrates 7, 8.
