Abstract
A liquid crystal display includes a liquid crystal cell; a back light including a light source; and a laminated polarizing plate including a protective film, a polarizing film, and a retardation film in sequence from the side of the back light, wherein the angle defined by any one of the long and short sides of the polarizing plate and the absorption axis of the polarization film is 45°, the retardation film has an in-plane slow axis parallel or orthogonal to the absorption axis of the polarizing film, and the liquid crystal display satisfies the formula: M=|δTD/δMD|≧2.0, where M represents the ratio of the dimensional change rates in the entire polarizing plate, δMD (%) represents a percent change of the polarizing plate in the absorption axis direction, and δTD (%) represents a percent change of the polarizing plate in the direction orthogonal to the absorption axis.
