Abstract: A display apparatus includes a display panel, a polarizing plate, and a patterned retarder. The display panel includes a first substrate including a signal line and a pixel. A second substrate faces the first substrate. An image display device is disposed between the first and second substrates. The first substrate is disposed in a position to which external light is incident. The polarizing plate is disposed above the first substrate of the display panel. The patterned retarder is disposed between the polarizing plate and the signal line. The patterned retarder retards the external light such that the external light reflected by the signal line does not pass through the polarizing plate.

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.
