摘要： A polarizer includes a reflective polarizer main body and an Rth compensation layer. The reflective polarizer main body includes a repetitively laminated structure, the repetitively laminated structure including two layers of different refractive indices repetitively disposed on one another. The Rth phase compensation layer is disposed at one side of the reflective polarizer main body. The Rth phase compensation layer is configured to compensate for a phase difference in an Rth direction.

摘要： A liquid crystal display includes a liquid crystal panel, a polarizing plate on a surface of the liquid crystal panel and having a polarizing axis; and a compensation film between the liquid crystal panel and the polarizing plate, and having an optical axis at which light passes through the compensation film. When a surface of the compensation film is referred to as a x-y plane, a plane passing through an x-axis and vertical to the optical axis of the compensation film is referred to as an x-y′ plane. A first retardation value (Ro′) of the compensation film is (nx−ny′)d, and a second retardation value (Rth′) is [(nx+ny′)/2−nz′]d, and the first and second retardation values (Ro′) and (Rth′) satisfy the following Formula of 0.92≦Rth′/Ro′≦4.75, where ‘n’ denotes a refractive index and ‘d’ denotes a thickness of the compensation film in a z-axis direction.
