Patent ID: 7139058

Claim:
An array substrate for an in-plane switching liquid crystal display device, comprising: a substrate; a plurality of gate lines arranged in a first direction on the substrate; a plurality of data lines crossing the plurality of gate lines to define a plurality of pixel regions, each of the pixel regions consists of four sub-pixel regions; a plurality of switching elements, each switching element disposed at the crossing of the gate and data lines, each of the four-sub-pixel regions are individually controlled by one of the plurality of switching elements; a plurality of pixel electrodes, each of the pixel electrodes disposed in one of the four sub-pixel regions; and a plurality of common electrodes, each of the common electrodes alternatively arranged with each of the pixel electrodes to form a plurality of blocks in each of the four sub-pixel regions, wherein two of the sub-pixel regions include an n-number of the blocks, and two of the sub-pixel regions include an (n+2)-number of the blocks (n is a natural number).
