Abstract
A color filter substrate C includes an orientation filmprovided on one surface of another glass substrateand an optical compensation layerprovided on the other surface of the glass substrateand formed from a plastic film. The two substrates are disposed such that the orientation films thereof oppose each other, and polarization platesandare disposed on the outer sides of the two substrates, and a liquid crystal layerhaving a positive refractive index anisotropy is provided between the orientation films. The optical compensation layerhas a negative one axial refractive index anisotropy and can cancel a retardation produced in the liquid crystal layerthereby to suppress white floating of a black display portion.
