Abstract

An LCD including a wire grid polarizer is provided. The wire grid polarizer includes a plurality of grid patterns formed directly on the top or bottom surface of a bottom substrate of a liquid crystal panel. The wire grid polarizer is formed directly on a bottom glass substrate where TFTs and liquid crystals are formed, making it possible to reduce production costs due to the removal of an existing polarizing film, to reduce a total thickness of the LCD, and to achieve brightness enhancement.
