A liquid crystal display which generation of reverse twist is prevented, capable of displaying an excellent image having a wide visibility angle property, and containing no display irregularity is provided. The liquid crystal display comprises a liquid crystal layer formed by sandwiching a liquid crystal substance in between a color filter substrate and an electrode substrate having a pixel electrode and a common electrode provided parallel to the substrate surface, the color filter substrate has a black matrix, a color filter composed of coloring patterns of a plurality of colors, and a protective layer formed to cover the above-mentioned black matrix and color filter, and the black matrix has an electric conductivity of 9.0×10-9 S/cm or less and the coloring pattern has an electric conductivity of 2.0 ×10−10 S/cm or less.
