Abstract
A color liquid crystal display device contains a color filter substrate, a counterelectrode substrate disposed to oppose the color filter substrate via a sealing material disposed in contact with peripheral portions of the color filter substrate and the counterelectrode substrate, and a liquid crystal layer sealed between the color filter substrate and the counterelectrode substrate and surrounded by the sealing material. The color filter substrate contains a transparent substrate, a black matrix and a plurality of colored layers of plural colors, the black matrix and the colored layers being formed in a predetermined pattern in a first region on the transparent substrate, and a resin layer having substantially same thickness as that of the black matrix and formed in a second peripheral region on the transparent substrate positioned peripherally adjacent to the first region. The sealing material is in contact with the resin layer and a black matrix portion in periphery of the first region. A method for producing the color filter substrate involves the steps for forming the resin layer having substantially the same thickness as that of the black matrix.
