Patent ID: 7633582

Claim:
A liquid crystal display comprising: a liquid crystal display cell; two polarizers respectively provided on outer surfaces of the liquid crystal display cell; and two biaxial plates respectively provided between the two polarizers and the liquid crystal display cell, wherein the retardation of at least one of the two biaxial plates satisfies the following formulae (5) and (6): 82.38< R 0(450)+0.41 ×Rth (450)<107.35 (5) −910.5< R 0(450)−5.5 ×Rth (450)<−690.5 (6) where R0(450) represents the in-plane retardation of the at least one of the two biaxial plates at a wavelength of 450 nm, and Rth(450) is the value calculated by Rth=[[n x +n y ]/2−n z ]×d (where n x , n y and n z represent the three-dimensional refractive indexes of the at least one of the two biaxial plates as the refractive indexes in the direction of the x-axis, y-axis and z-axis, respectively, and d represents the thickness of the at least one of the two biaxial plates) for the at least one of the two biaxial plates at a wavelengths of 450 nm.
