ABSTRACT:
A transparent insulating film having a low adsorption characteristic of organic elements such as silicon dioxide is formed on a glass substrate carrying transparent electrodes formed thereon. The surface of the transparent insulating film is rubbed to form micro-grooves aligned in a predetermined direction. Two glass substrates having internal surfaces carrying micro-grooves formed in the above-mentioned manner are spaced against and adhered to each other and sealed through the use of a glass frit or glass paste, between which liquid crystal compositions are filled.
