Patent ID: 6922222

Claim:
A liquid crystal display apparatus, comprising: a liquid crystal cell; polarizers provided on both sides of said liquid crystal cell; quarter wavelength layers provided between said respective polarizers and said liquid crystal cell, each of said quarter wavelength layers having a retardation in an in-plane direction that is substantially set at a quarter wavelength of a wavelength of transmitted light; and a phase difference layer, provided between at least one of said quarter wavelength layers and said liquid crystal cell, which has a retardation in a perpendicular direction, and optically compensates said liquid crystal cell, wherein said quarter wavelength layers have nz 4 substantially equal to (nx 4 +ny 4 )/2, where main refraction indexes in in-plane directions are nx 4 and ny 4 , while a main refraction index in a normal direction is nz 4 .
