  • Patent number: 7381505
    Abstract: A color filter substrate for a liquid crystal display device includes sub-pixel regions of three primary colors of R, G, and B formed by colored layers of the three primary colors, and sub-pixel regions of complementary colors of the three primary colors, namely, C, M, and Y, each formed by arranging two of the colored layers of the three primary colors such that the two colored layers are adjacent to each other. The colored layer thickness in each complementary-color sub-pixel region is larger than the colored layer thickness in each primary-color sub-pixel region. To compensate for the thickness difference, a transparent resin layer having no influence on the transmittance of light is formed such that the surfaces of the colored layers contacting a liquid crystal layer are leveled.
