Abstract:
1. An array substrate for a liquid crystal display device, comprising: a substrate; first and second gate lines on the substrate, wherein the first and second gate lines are arranged in a first direction; a common line arranged in the first direction and between the first and second gate lines; first and second data lines arranged in a second direction, the first and second data lines crossing the first and second gate lines and the common line to define a pixel, the pixel consisting of first, second, third and fourth sub-pixels, wherein the fourth sub-pixel is smaller than the first, second and third sub-pixels, and the first, second and third sub-pixels have the same size; a thin film transistor at each crossing point of the first and second gate lines and the first and second data lines; a common electrode in the first, second, third and fourth sub-pixels and connected to the common line; and pixel electrodes in the first, second, third and fourth sub-pixels and connected to the thin film transistor, wherein the first sub-pixel has a first width and a first length, the second sub-pixel has the first width and a second length, the third sub-pixel has a second width and a third length, and the fourth sub-pixel has the second width and a fourth length, wherein the first width is wider than the second width, the first length equals to the second length, and the first and second lengths are shorter than the third length and are longer than the fourth length, and wherein the first, second and third sub-pixels correspond to red, blue and green sub-pixels, and the fourth sub-pixel corresponds to a white sub-pixel.
