A liquid crystal display of transmission type comprises a light source, a polarizing film, a liquid crystal cell and another polarizing film in this order. An optical compensatory sheet is further provided between the liquid crystal cell and the polarizing film on a light source side or between the liquid crystal cell and the polarizing film on a display side. The optical compensatory sheet comprises a transparent support and an optically anisotropic layer. The optically anisotropic layer contains a discotic compound having a discotic plane. The discotic plane is inclined from a surface of the support surface at an angle. The angle varies along a direction of depth of the optically anisotropic layer. The liquid crystal display has a difference in chromaticity (ΔCuv) of 0.05 or less. The difference is measured between an image seen frontally and an image seen rightward or leftward at a viewing angle of 60°.
A liquid crystal display of transmission type which comprises a light source, a polarizing film, a liquid crystal cell and another polarizing film in this order, an optical compensatory sheet being further provided between said liquid crystal cell and said polarizing film on a light source side or between said liquid crystal cell and said polarizing film on a display side, said optical compensatory sheet comprising a transparent support and an optically anisotropic layer, which contains a discotic compound having a discotic plane, which is inclined from a surface of the support surface at an angle varying along a direction of depth of the optically anisotropic layer, wherein the liquid crystal display has a difference in chromaticity of 0.05 or less between an image seen frontally and an image seen rightward or leftward at a viewing angle of 60°, wherein a diffusing film is provided on a display side surface of the polarizing film on the display side, said diffusing film having a diffusing layer in which first and second transparent fine particles are dispersed in a transparent resin, said first transparent fine particles having a mean particle size in the range of 0.6 to 1.8 μm, said second transparent fine particles having a mean particle size in the range of 2.2 to 4.7 μm, said first and second transparent fine particles having refractive indices that are different from a refractive index of the transparent resin, wherein the first and second fine particles are plastic beads, and wherein the difference in refractive index between the transparent fine particles and the transparent resin is in the range of 0.02 to 0.15.
