Abstract
A liquid crystal display element has a liquid crystal cell contructed such that a liquid crystal layer composed of a liquid crystal composition having a positive dielectric anisotropy is homogeneously oriented between a pair of substrates provided with electrodes; a pair of polarizers disposed such that the liquid crystal layer is arranged between the polarizers; and a uniaxial medium disposed at least one of clearances between the liquid crystal layer and the both polarizers, the uniaxial medium having a positive optical anisotropy and an optical axis in a direction perpendicular to a substrate face. In the liquid crystal display element, products of refractive index anisotropy and thickness of the uniaxial medium are different from each other in accordance with the difference between displayed colors determined every display picture element.
