Claim 0:
1. An array substrate of an in-plane switching (IPS) mode display panel, the IPS display panel comprising a liquid crystal layer containing horizontally arranged liquid crystal molecules, the array substrate comprising a plurality of data lines, a plurality of scan lines, and a plurality of pixels, wherein the plurality of pixels are respectively driven by the corresponding scan lines and data lines, and wherein each of the plurality of pixels comprises a pixel electrode layer and a common electrode layer;
wherein the common electrode layer comprises a plurality of common electrode branches and a common electrode trunk connected to the plurality of common electrode branches; the pixel electrode layer comprises a plurality of interconnected pixel electrode branches;
wherein the plurality of pixel electrode branches are alternately arranged with the plurality of common electrode branches;
wherein each pixel electrode branch comprises a branch body and a branch end connected to the branch body, wherein the branch end is disposed at an end of the branch body adjacent to the common electrode trunk;
wherein the branch end comprises a first side, a second side and a third side, wherein the first side is disposed opposite the common electrode trunk to form a first gap, and wherein the second side and the third side are respectively disposed opposite to the common electrode branches on both sides of the pixel electrode branch to form a second gap and a third gap, respectively; a fourth gap is formed between the branch body and the common electrode branch on each side of the pixel electrode branch;
wherein of the first gap, the second gap and the third gap, a width value of at least one gap is smaller than a width of the fourth gap, so that a strength of an electric field between the branch end and the common electrode trunk is increased and that a ratio of an influence of the respective scan line and the respective data line to a horizontal electric field component of the electric field formed between the branch end and the common electrode trunk is reduced;
wherein a width of the first gap is smaller than the width of the fourth gap; wherein let the width of the first gap be d1, and the width of the fourth gap be w, then a ratio of d1 to w lies between 0.25 and 0.65, that is, 0.25≤d1/w≤0.65.
