Patent ID: 7719652

Claim:
An array substrate for an in-plane switching liquid crystal display device, comprising: gate lines arranged in a first direction on a substrate; data lines crossing the gate lines to define a pixel region; a switching element at a crossing of the gate and data lines; a pixel electrode in the pixel region; and a common electrode alternatively arranged with the pixel electrode, wherein the pixel region consists of first and second areas divided by a straight line parallel to the first direction, and the first area of the pixel region consists of an n-number of blocks (n is natural number) and the second area of the pixel region consists of an (nα2)-number of blocks, wherein the straight line is one of a common line and a horizontal portion of the pixel electrode, and wherein the first area of the pixel region is adjacent to a third area of a next pixel region along the first direction, and the second area of the pixel region is adjacent to a fourth area of the next pixel region along the first direction, wherein the fourth area of the next pixel region consists of an n-number of blocks and the third area of the next pixel region consists of an (n+2)-number of blocks.
