PCT No. PCT/JP94/02067 Sec. 371 Date Jul. 27, 1995 Sec. 102(e) Date Jul. 27, 1995 PCT Filed Dec. 8, 1994 PCT Pub. No. WO95/16936 PCT Pub. Date Jun. 22, 1995An electrode substrate for liquid crystal display devices is constructed with a resin substrate 4, a cured coating 3, a cured coating 2 and an ITO film 6 laminated in that order. The resin substrate 4 comprises a transparent resin which is a copolymer containing not less than 20% by weight of maleimide type monomer units, having a crosslinked structure and having a glass transition temperature of not lower than 160 DEG C. and not higher than 200 DEG C., and has a thickness of 0.1 to 0.8 mm. The cured coating 3 is a cured coating comprising a polyvinyl alcohol crosslinked with an epoxysilane represented by the formula R1SiX3 wherein R1 is an organic group of 1 to 10 carbon atoms having a glycidyl group and X is a hydrolyzable group. The cured coating 2 is a siloxane type cured coating containing fine silica particles. The ITO film 6 is an ITO film having a grainy surface with grains of a diameter of not larger than 500 nm, formed at a substrate temperature of not higher than 100 DEG C., and having a thickness of 15 to 500 nm.
