Abstract:
1. A liquid crystal display, comprising: a thin film transistor array substrate comprising a red sub-pixel region, a green sub-pixel region and a blue sub-pixel region; a color filter array substrate oppositely disposed to the thin film transistor array substrate, wherein the color filter array substrate comprises a black matrix formed in a matrix shape to define the sub-pixel regions, a red (R) color filter corresponding to the red sub-pixel region, a green (G) color filter corresponding to the green sub-pixel region, a white (W) color filter corresponding to the blue sub-pixel region, and an overcoat layer covering the black matrix and the color filters, wherein the white color filter is formed in a same material as the overcoat layer; a liquid crystal layer formed between the color filter array substrate and the thin film transistor array substrate; and a backlight unit comprising a light emitting diode (LED) unit which provides white light having an adjusted blue spectrum to a surface of the color filter array substrate.
