发明名称 Color filter for transflective type liquid crystal display
摘要 The main object of the present invention is to provide a color filter for a transflective type color liquid crystal display which is easily produced and capable of displaying the same color tone with both of a reflecting light and a transmitting light, and shows light scattering in a reflective light region. In order to attain the above mentioned object, the present invention provides a color filter for transflective type color liquid crystal display comprising a transparent substrate and a reflective light coloring layer and a transmissive light coloring layer formed on the transparent substrate, wherein, a convex-concave is formed on a surface of a liquid crystal layer side of the reflective light coloring layer, and an average thickness of the reflective light coloring layer is formed to be thinner than the thickness of the transmissive light coloring layer, and a refractive index difference between the reflective light coloring layer and a layer in contact with the surface of the convex-concave formed side of the reflective light coloring layer, is 0.1 or more. Further, a main object of the present invention is to provide a color filter for transflective type liquid crystal display comprising a transparent membrane pattern region obtained by laminating: a transparent substrate; a transparent membrane pattern layer comprising a transparent membrane formed in a pattern on the transparent substrate; and a coloring layer formed so as to cover the transparent membrane pattern layer.
