Array substrate and display panel

A display panel of an in-plane switching (IPS) mode, comprising a color filter substrate and an array substrate, and further comprising a liquid crystal layer arranged between the color filter substrate and the array substrate and containing horizontally arranged liquid crystal molecules, wherein the color filter substrate and the array substrate are aligned and bonded together, wherein the array substrate comprises 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.
