Patent ID: 7643116

Claim:
A liquid crystal display device comprising: a liquid crystal panel made by filling vertical alignment-type liquid crystals into a space between a pair of substrates; a first polarizing plate placed on one side of the liquid crystal panel; and a second polarizing plate placed on other side of the liquid crystal panel, wherein the liquid crystal display device has, between the first and second polarizing plates, at least one of a first retardation layer in which an in-plane retardation in the wavelength range of 380 to 780 nm increases as a wavelength of light increases, and a second retardation layer in which a negative retardation in the wavelength range of 380 to 780 nm decreases as the wavelength of light increases, wherein when the in-plane retardation of the first retardation layer is denoted by Raplate (nm), the in-plane retardation Raplate of the first retardation layer is in the range represented by the following expression: (0.235±0.02)×λ−RTAC/2−10±20 where RTAC is a negative retardation of a protective layer for one of the first and second polarizing plates, the protective layer being adjacent to the first retardation layer without an optical intermediate, the negative retardation being at green wavelength, and λ is the wavelength of light.
