摘要： A color filter substrate for use in a fringe-field switching mode liquid crystal display wherein the color filter substrate and an array substrate provided with a comb-shaped pixel electrode having an electrode width of 10 µm or less are arranged facing each other with a liquid crystal layer interposed therebetween. The color filter substrate comprises a transparent substrate, a black matrix provided on the transparent substrate, comprising an organic pigment as a main coloring agent, a red pixel, a green pixel and a blue pixel which are provided in regions partitioned by the black matrix on the transparent substrate and each have a relative dielectric constant of 2.9 or more but 4.4 or less, as measured at a frequency at which the liquid crystal is driven, and a transparent resin layer provided on the red pixel, the green pixel and the blue pixel. The relative dielectric constant of each of the color pixels falls within ±0.3 of an average relative dielectric constant of the red pixel, the green pixel and the blue pixel.
