Active matrix liquid crystal display panel having particular optical compensation layer

Abstract

An active matrix liquid crystal display panel by which a good display characteristic can be obtained without suffering from gradation reversal over a wide visibility angle range. A liquid crystal layeris formed such that the thickness thereof varies in accordance with transmission wavelengths of color layersandso that a very good display which does not exhibit any coloring in whichever direction it is viewed may be obtained. An active matrix substrate A includes a plurality of opposing electrodes, a plurality of pixel electrodesparallel to the opposing electrodes, a thin film transistor, and an orientation filmall formed on a glass substrate. 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.
