Abstract

An LCD including a wire grid polarizer is provided. A liquid crystal panel forming pixels is stacked on a backlight unit, and one or more wire grid polarizers are disposed on top or bottom substrates constituting the liquid crystal panel. The wire grid polarizer includes a first grid layer having one or more first grid patterns on a substrate, and a second grid layer having one or more second grid patterns formed on the first grid patterns. A wire grid polarizer includes a first grid layer having first grid patterns on a substrate, and second grid patterns formed on the first grid patterns, and the wire grid polarizer is disposed on an LCD or a backlight unit, thereby preventing distortion of image and reduction of brightness and achieving high durability.
