Claim Text:
1. 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 comprising: a transparent substrate; a black matrix provided on the transparent substrate, comprising an organic pigment as a main coloring agent; color pixels which contain a red pixel, a green pixel, and a blue pixel and are provided in regions partitioned by the black matrix on the transparent substrate, each of the color pixels having a relative dielectric constant of 2.9 or more but 4.4 or less, as measured at a frequency at which the liquid crystal display is driven; and a transparent resin layer provided on the red pixel, the green pixel and the blue pixel, wherein 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, a coloring agent of the black matrix comprises the organic pigment in an amount of 92 mass % or more based on a whole amount of the coloring agent, and comprises carbon as a balance, and a main coloring agent of the green pixel is a halogenated zinc-phthalocyanine pigment.
