LIQUID CRYSTAL ELEMENT

Title:

LIQUID CRYSTAL ELEMENT

Document Type and Number:

Japanese Patent JPS6263918

Kind Code:

A

Abstract:

PURPOSE: To form a liquid crystal element having color picture elements of high transmittance by providing a protective layer having a specific coefft. of linear expansion between a color filter layer and transparent electrodes.

CONSTITUTION: The color filter layers 14 which are respectively one picture element of a BGR color filter are provided on a substrate 11a and the transparent electrode 12a is provided via the protective layer 15 on said color filter layer 14. The protective layer 15 is exemplifed by a material selected from materials having the coefft. α of linear expansion most adequately 0.05W5 times the coefft. of linear expansion of the transparent electrode 12a. More specifically, SiO2 (α; 6×10-6/°C) is suitable.
