Abstract: A liquid crystal display device comprises an array substrate, a liquid crystal layer, and a color filter substrate. The liquid crystal layer is disposed between the array substrate and the color filter substrate. The color filter substrate includes a base material, an overcoat, a color filter layer and first transparent electrode patterns. The overcoat is disposed between the base material and the liquid crystal layer. The color filter layer is disposed between the base material and the overcoat, and includes color filter elements separated from each other and black matrixes. The first transparent electrode patterns are disposed between the overcoat and the liquid crystal layer, and are separated from each other and opposed to the black matrixes. A width of each of the black matrixes is equal to or greater than a width of each of the first transparent electrode patterns.
