  • Patent number: 5495354
    Abstract: A method of producing a color filter for a liquid crystal display which can improve the evenness of a color filter surface layer by eliminating the difference in height between black matrices and color elements. The black matrices are formed on a transparent insulating layer and the color elements of red, green and blue are formed between the black matrices. On the black matrices, additional black matrices are formed with the same height as the color elements by electroplating, and a protective layer and a transparent conductive layer are formed thereon. Alternatively, the transparent conductive layer and the color elements are formed on the transparent insulating substrate in turn, the black matrices are formed between the respective color elements up to the same height as the color elements, and then the protective layer is formed thereon.
