Liquid crystal display
View Patent ↗The present invention relates to a liquid crystal display (LCD) and a method of manufacturing the same. In the present invention, a wire grid polarizing pattern is formed on at least one of thin film transistor and color filter substrates in a manufacturing process thereof. According to the present invention, the thickness of an LCD panel can be reduced as compared with a method of attaching an existing polarizer to an LCD panel, and the wire grid polarizing pattern can be built in an LCD panel without increasing the number of masking processes.
