Abstract

A color filter substrate includes a substrate, a black matrix, a color filter layer and a common electrode. The black matrix is formed on the substrate and partially distributed on the substrate, wherein the black matrix further includes a resin layer and a light shield layer for lowering the reflectance, and improving the light shielding capability. The color filter layer is formed on the substrate where it is not covered by the black matrix. The common electrode is formed on top of the color filter layer, and the black matrix.
