Abstract

A wire grid polarizer is provided. The wire grid polarizer includes a first grid layer with at least one first grid pattern on a substrate, a second grid pattern formed using a metal on the first grid pattern, and a light absorbing layer stacked on the second grid pattern to absorb light incident from the exterior. Since the wire grid polarizer has both an absorbing function and a reflecting function, brightness enhancement can be achieved, without lowering a bright room contrast ratio.
