Claim:
A liquid crystal display device, comprising: a liquid crystal display element formed so that a liquid crystal layer is disposed between a pair of substrates; a pair of polarizers disposed so as to flank said liquid crystal display element; and at least one optical retardation compensator plate disposed between said liquid crystal display element and said polarizers, said at least one optical retardation compensator plate being represented by an inclining refractive index ellipsoid, wherein ratios of a variation in a refractive index anisotropy, Δn L , of the liquid crystal material of said liquid crystal layer with wavelengths of light and of a variation in a refractive index an isotropy, Δn F , of the optical retardation compensator plate with wavelengths of light are controlled so as to be different from one another and also are set within such a range that viewing angle dependency does not cause coloration of the liquid crystal display, and wherein a ratio, Δn L (450)/Δn L (550), of a refractive index anisotropy, Δn L (450), of the liquid crystal material of said liquid crystal layer to light having a wavelength of 450 nm and a refractive index anisotropy, Δn L (550), thereof to light having a wavelength of 550 nm, and a ratio, Δn F (450)/Δn F (550), of a refractive index anisotropy, Δn F (450), of said at least one optical retardation compensator plate to light having a wavelength of 450 nm and a refractive index anisotropy, Δn F (550), thereof to light having a wavelength of 550 nm satisfy the inequality: 0≦(Δ n L (450)/Δ n L (550)−1)/(Δ n F (450)/Δ n F (550)−1)<0.35.
