Abstract:
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 said liquid crystal cell, said biaxial compensation films including an optical dielectric material layer; and polarization plates provided on outer surfaces of said biaxial compensation films, wherein retardation values (ny-nx)*d and (nz-nx)*d of the biaxial compensation films are respectively within ranges of âˆ’30+5 nm and âˆ’RLC/4+15 nm, where â€œdâ€  is set as a cell gap of the liquid crystal cell, â€œRLCâ€  is set as a phase retardation value of the liquid crystal layer, an axis perpendicular to planes made by the pair of transparent 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.
