摘要:
A liquid crystal display showing a high contrast and reduced in color shift depending on the viewing angle is provided.The liquid crystal display device comprises a liquid crystal cell having a retardation value Re1(400) at 400 nm and a retardation value Re1(550) at 500 nm in the black state; and at least one layer of optically anisotropic layer formed of a composition comprising at least one species of liquid crystalline compound, having a retardations value Re2(400) at 400 nm and a retardation value Re2(550) at 550 nm, wherein Re2(400) and Re2(550) of said optically anisotropic layer, and retardations values Re1(400) and Re1(550) satisfy the relational expression (1) below: 0.9≦α2/α1≦1.1 Relational Expression (1) where, α1=Re1(400)/Re1(550) and α2=Re2(400)/Re2(550).
