ABSTRACT:
A process for producing an electrode substrate for use in a liquid crystal device in which a laminate film of a transparent conductive film and a metal film is formed on a first side of a transparent substrate. The laminate film is pattern-etched so as to form islands of the laminate film in a predetermined pattern. A photosensitive anaerobic colored resin is applied on the transparent substrate on which the islands of laminate film arranged in the predetermined pattern. The transparent substrate is uniformly exposed to a light from a second side of the substrate opposite to the first side in an oxygen-containing atmosphere. Unexposed portions of the photosensitive anaerobic resin are removed so as to leave the photosensitive anaerobic resin only in the spaces between adjacent islands of the laminate film, for forming a light-shielding film in each of the spaces. The metal film of each laminate film island is etched so as to remove unnecessary portions of the metal film, thereby forming metal electrodes wired along edges of the transparent conductive film.
