Patent ID: 8704231

Claim:
An array substrate of a thin film transistor liquid crystal display (TFT-LCD), comprising: a base substrate; gate lines and data lines formed on the substrate, the gate lines and the data lines crossing with each other to define a plurality of pixel units each of which comprises a thin film transistor, a first electrode layer and a second electrode layer, wherein the first electrode layer is separated from the second electrode layer through an insulation layer; the first electrode layer comprises a plurality of first electrodes separated by openings in the first electrode layer; the second electrode layer comprises a plurality of second electrodes separated by openings in the second electrode layer; the second electrodes comprise overlapping electrodes each of which completely overlaps with the first electrodes and non-overlapping electrodes whose edges are completely located within an region corresponding to the openings in the first electrode layer; and the overlapping electrodes and the non-overlapping electrodes are alternately distributed, and wherein the width “a” of each first electrode, the opening width “b” of the first electrode layer, the width “c” of each second electrode, and the opening width “d” of the second electrode layer have the following relationship: width “d” of the second electrode layer have the following relationship: c+n(c+d)<a<c+2d+n(c+d), c<b<c+2d, and a+b=2c+2d+n(c+d), wherein “n” is an integer greater than or equal to zero.
