Patent ID: 8174655

Claim:
A liquid crystal display device, comprising: first and second substrates facing each other; gate and data lines formed on the first substrate and crossing each other to define a pixel region, wherein the pixel region is horizontally divided as upper part, center part and lower part; a first common electrode in the upper part and the lower part of the pixel region, the first common electrode having a plate shape, wherein the first common electrode covers the upper and lower parts; a plurality of first pixel electrodes directly over the first common electrode and at a first fixed interval in the upper and lower parts of the pixel region; a second pixel electrode alternately arranged with a second common electrode at a second fixed interval in the center part of the pixel region, wherein the first and second common electrodes are formed on different layers; an electrode having two opposite isosceles triangles symmetric with each other, wherein the electrode is positioned at a center line halving the pixel region at the direction of data line; and a layer of liquid crystal molecules between the first and second substrates, wherein a first width of each of the first pixel electrodes is less than a second width of the second pixel electrodes.
