摘要:
Disclosed is a liquid crystal display comprising a liquid crystal cell including a pair of transparent substrates, with orientation layers deposited on inner surfaces thereof, and a liquid crystal layer of liquid crystal material injected between the substrates; biaxial compensation films provided on outer surfaces of the liquid crystal cell, the biaxial compensation films including an optical dielectric material layer; and polarization plates provided on outer surfaces of the biaxial compensation films, wherein if “d” is set as a cell gap of the liquid crystal cell, “RLC” is set as a phase retardation value of the liquid crystal layer, an axis perpendicular to planes made by the substrates is set as a z-axis, x-axis and y-axis are formed on a planar surface of the substrates, and refractive indices of molecules comprising the biaxial compensation films in the x, y and z directions are denoted by nx, ny and nz, retardation values (ny−nx)*d and (nz−nx)*d of the biaxial compensation films being respectively within ranges of −30±5 nm and −RLC/4±15 nm.
