Title: Production of color filter
Inventor: WATANABE EIZABURO
IPC: G02B5/20
Filed: 1990-03-06
Abstract: PURPOSE:To simplify the process and to cope with the increase of the substrate size by forming an electrophotographic sensitive body, which does not absorb the visible light range, on a conductive supporting body and forming an electrostatic latent image by electrification and exposure and immersing it in electrophotographic developer where colored resin is dispersed to form a colored pattern. CONSTITUTION:An electrophotographic sensitive body 3 which does not absorb the visible light range is formed on a conductive supporting body 1 and is electrified and exposed to form an electrostatic latent image, and the conductive supporting body 1 is immersed in electrophotographic developer 6, where colored resin is dispersed in carrier liquid, to form a desired colored pattern. After color patterns of required colors are formed, a transparent substrate and the conductive supporting body 1 are closely brought into contact with each other, and light irradiation is applied to transfer the colored layer and the electrophotographic sensitive body layer to the transparent substrate. Thus, the coating process is deleted, and the pattern form of a color filter is arbitrarily determined by exposure, and the time required for production of the color filter is shortened. Since the used energy is small, this method easily copes with the large substrate size.
