Problems solved by technology

Under normal operation, the liquid crystal molecules can be arranged stably, but when there is an external force to press the liquid crystal display panel, due to the change of the distance (cell gap) between the two substrates, the electric field changes at the pressed place, so that the liquid crystal molecules at the pressed place disordered arrangement
More specifically, when the liquid crystal panel is subjected to external pressure (such as finger pressure), because the liquid crystal molecules are affected by the above-mentioned distorted electric field, they cannot quickly return to the original alignment state, which often causes finger mura and seriously affects LCD panel display quality

Abstract

The invention provides a display panel which comprises a first substrate, a second substrate, a liquid crystal layer, a shading pattern layer and a plurality of pixel structures. The liquid crystal layer is arranged between the first substrate and the second substrate and comprises a plurality of negative liquid crystal molecules. Each pixel structure comprises a first electrode and a second electrode. The first electrode has an electrode opening and a first finger portion extending into the electrode opening. The second electrode has two second finger portions overlapping the electrode opening. The first finger-shaped parts and the two second finger-shaped parts are alternately arranged in the first direction and extend in the second direction. Voltage is applied between the first electrode and the second electrode of each pixel structure, and a light-transmitting area and a first dark fringe area are arranged between one of the two second finger-shaped parts and the first finger-shaped part. The first dark fringe region has a first width in the second direction on a side of the second finger portion. A plurality of opening areas of the shading pattern layer respectively have an opening length in the second direction, and the percentage value of the first width and the opening length is less than 5%.

Description

technical field [0001] The present invention relates to a display technology, in particular to a display panel. Background technique [0002] At present, the performance requirements of the market for LCDs are towards high contrast, no grayscale inversion, little color shift, high luminance, high color richness, and high color saturation. , fast response (response) and wide viewing angle and other characteristics. Technologies capable of achieving wide viewing angle requirements include, for example, twisted nematic liquid crystal (TN) plus wide viewing film (wide viewing film), in-plane switching (IPS) liquid crystal display, fringe field switching Type (fringe field switching, FFS) liquid crystal display and multi-domain vertically aligned (multi-domain vertically aligned, MVA) liquid crystal display. Among them, the coplanar switching type and the fringe field switching type liquid crystal display have a better wide viewing angle effect than the twisted nematic liquid c...
