ABSTRACT:
A liquid crystal electro-optical device which is a dispersion-type liquid crystal electro-optical device comprising an electro-optical modulating layer containing a liquid crystal material and a light-transmitting support, characterized by that there is established a force-relaxation portion for relaxing interfacial attractive force between said liquid crystal material and said light-transmitting support, and a process for fabricating the same. The force-relaxation portion can be an uncured transparent resinous material, a material obtained by decomposing the liquid crystal, a reformed surface portion, or a material selected from the group selected from lecithin, stearic acid, hexadecyltrimethylammonium bromide, octadecylmalonic acid, dibasic fatty acids, crown ethers, octadecylamine hydrochloride, and hexamethyldisilazane.
