Abstract:
1. A liquid crystal display comprising: a liquid crystal cell; a back light including a light source disposed at any one of an edge and a corner in the rear of the liquid crystal cell; 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, the protective film has a thickness of 10 to 60 μm and a tensile modulus of 3.0 to 8.0 GPa in a direction parallel to the absorption axis of the polarizing film, the polarizing film has a thickness being 10 to 50% of the thickness of the protective film, the retardation film comprises a cyclic olefin resin and has a thickness being 30 to 100% of the thickness of the protective film, and a dimensional change rate δMD of the polarizing plate in the absorption axis direction of the polarizing film and a dimensional change rate δTD of the polarizing plate in a direction orthogonal to the absorption axis of the polarizing film satisfy the formula: where M represents the ratio of the dimensional change rates in the entire polarizing plate, δMD (%) represents a percent change in the length of the polarizing plate after being dried at 60° C. for 100 hours to the initial length of the polarizing plate in the absorption axis direction at 25° C. and a 60% RH, and δTD (%) represents a percent change in the length of the polarizing plate after being dried at 60° C. for 100 hours to the initial length of the polarizing plate in the direction orthogonal to the absorption axis at 25° C. and 60% RH.
