Abstract: A polarizer includes a first laminated structure having a first layer with a first refractive index and a second layer with a second refractive index, wherein the first and second refractive indices are different from each other. A buffer layer is disposed on the first laminated structure. A second laminated structure in the polarizer has a third layer with a third refractive index and a fourth layer with a fourth refractive index, wherein the third and fourth refractive indices are different from each other.

Abstract: 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.
