Title:
MANUFACTURE OF LIQUID-CRYSTAL DISPLAY DEVICE
Document Type and Number:
Japanese Patent JPS5844419
Kind Code:
A
Abstract:

PURPOSE: To seal two substrates with high adhesive strength without any spread of sealing layers, by forming sealing layers of adhesives to be cured by ultraviolet-ray irradiation on those two substrates respectively, and then previously curing one sealing layer and using as a spacer.

CONSTITUTION: On one substrate 1, a sealing layer 2 of an adhesive to be cured by ultraviolet-ray irradiation is formed by screen printing. Said adhesive is cured by ultraviolet-ray (UV) irradiation to complete adhesion to the substrate, and the sealing layer 2 serves as a spacer for deciding on the gap of liquid-crystal cells. On the other substrate 1', another sealing layer 2' is formed at the outside of the sealing layer 2. Those two substrates are pressed against each other to be superposed while the gap between both substrates is nearly equal to the thickness of the sealing layer 2 of one substrate 1. In this state, the UV irradiation is carried out to cure the sealing layer 2', thus obtaining a liquid-crystal sealed container.
