Patent ID: 8045104

Claim:
An in-plane switching mode liquid crystal display comprising: a TFT array substrate comprising a data line, a pixel electrode and a common electrode, and the data line, the pixel electrode and the common electrode have at least one bent structure; a color filter array substrate opposite to the TFT array substrate, the color filter array substrate comprising a black matrix covering an area corresponding to at least the data line and the common electrode; and a liquid crystal layer formed between the TFT array substrate and the color filter array substrate, wherein the black matrix comprises two first black matrix lines covering an area where light leakage is minimal, and two second black matrix lines covering an area where light leakage is excessive, the second black matrix lines having a line width larger than the line widths of the first black matrix lines, wherein the area where light leakage is minimal and the area where light leakage is excessive are formed by the bent structure of the common electrode, and wherein one of the two first black matrix lines and one of the two second black matrix lines are connected with a predetermined angle to be opposite to each other and to be asymmetrical with respect to each other, and one of the two first black matrix lines and the other of the two second black matrix lines are disposed in parallel.
