Abstract

The invention relates to a pixel structure, which comprises a substrate, a scanning line, a first data wire and a first pixel unit, wherein the scanning line and the first data wire are arranged on the substrate; the first pixel unit comprises a first active element and a first pixel electrode; the first active element, the scanning line and the first data wire are electrically connected; the first pixel electrode is electrically connected with the first active element; the first pixel electrode is provided with a strip pattern which is parallel to the scanning line in general and a plurality of branches which are electrically connected with the strip pattern; one side of the strip pattern is connected with the branches extending to the scanning line, and the other side of the strip pattern is overlapped with part of the scanning line; and the overlapped width of the strip pattern and the scanning line is 40 to 90 percent of the width of the strip pattern. Therefore, the pixel structure has high aperture opening ratio, and can obtain good display quality.

Description

technical field [0001] The present invention relates to a pixel structure, and in particular to a pixel structure capable of improving display quality. Background technique [0002] The performance requirements of the market for LCD panels are towards high contrast ratio, no gray scale inversion, little color shift, high luminance, high color richness, Features such as high color saturation, fast response and wide viewing angle. At present, the technologies that can meet the requirement of wide viewing angle include twist nematic (TN) liquid crystal plus wide viewing film (wide viewing film), in-plane switching (IPS) liquid crystal display panel, fringe field A fringe field switching liquid crystal display panel, a multi-domain vertically aligned (MVA) liquid crystal display panel, and the like. [0003] The known multi-domain vertical alignment liquid crystal display panel utilizes the configuration of the alignment structure to make the liquid crystal molecules in differ...
