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 panel, the connection part 105 will become the main reason for the poor alignment of the liquid crystal molecules.
That is to say, when the liquid crystal panel is subjected to external pressure, the liquid crystal molecules are affected by the above-mentioned distorted electric field, and cannot quickly return to the original alignment state, resulting in finger press mura, which seriously affects the liquid crystal display panel. quality

Abstract

A pixel structure used for a baseplate comprises a first pixel electrode, a second pixel electrode and a top-grid film transistor. The first pixel electrode and the second pixel electrode are separately configured on an upper part of the baseplate. The top-grid film transistor is configured between the baseplate and the first pixel electrode and comprises a patterned semiconductor layer and a grid.

Description

technical field [0001] The present invention relates to a liquid crystal display panel, and in particular to a pixel structure in the liquid crystal display panel. Background technique [0002] At present, the market is oriented toward high contrast, no gray scale inversion, high brightness, high color saturation, and fast response for TFT-LCD. And wide viewing angle (viewing angle) and other directions. Currently common wide viewing angle technologies include: twisted nematic liquid crystal (TN) plus wide viewing film (wide viewing film), in-plane switching (In-Plane Switching, IPS) liquid crystal display, fringe field switching (Fringe Field Switching, FFS) liquid crystal display and multi-quadrant vertical alignment (Multi-domain Vertical Alignment, MVA) liquid crystal display. Taking the multi-quadrant vertical alignment liquid crystal display panel as an example, it can pass some alignment patterns, such as alignment protrusions or slits, so that the liquid crystal mo...
