Polarizing plate and optical display apparatus

Abstract

A polarizing plate for an optical display apparatus includes: a polarizer; and a retardation layer laminated on one surface of the polarizer, wherein the retardation layer includes a retardation film satisfying nx>nz>ny at a wavelength of 550 nm (Here, nx, ny, and nz refer to a refractive index of the retardation film in a slow axis direction, a refractive index of the retardation film in a fast axis direction, and a refractive index of the retardation film in a thickness direction at a wavelength of 550 nm.), an orientation direction of a main chain of a resin contained in the retardation film is about −5° to about +5° relative to a light absorption axis of the polarizer, and the retardation film has a degree of biaxiality of about 0.3 to about 0.7 at a wavelength of 550 nm.
