Abstract
A polarizer for a display device is disclosed. In one aspect, the polarizer includes a linear polarizer and a phase retardation layer on the linear polarizer and comprising a quarter-wave plate and a half-wave plate. The half-wave plate includes a refractive index anisotropic layer. The refractive index anisotropic layer has a refractive index Nx defined in a direction of an x axis, a refractive index Ny defined in a direction of a y axis, and a refractive index Nz defined in a direction of a z axis, wherein Nx=Nz>Ny.
