Problems solved by technology

However, liquid crystal molecules will experience different electric field magnitudes and directions under the action of a non-uniform electric field, causing some liquid crystal molecules to fall in unexpected directions, and produce undesired dislocation lines ( disclination line) and disclination node, which in turn affect the light transmittance of the display panel

Abstract

The invention discloses a pixel structure, comprising a substrate with surfaces, an insulating layer, and pixel electrodes. The insulating layer defines a first region and a second region surrounding the first region. The first region is provided with a first region top surface and the second region is provided with a second region top surface. A first distance from the first region top surface to the surface is smaller than a second distance from the second region top surface to the surface. The pixel electrode continuously extends from the first region top surface to the second region top surface, wherein the pixel electrode is provided with a backbone opening and a plurality of slit openings communicated with the backbone opening. The backbone opening is distributed along a cross track, so as to mark off a plurality of alignment regions. The slit openings in a same alignment region are parallel to each other, and a stripe portion of the pixel electrode is defined between two adjacent slit openings. The intersected position of the cross track is in the first region. Also provided is a display panel.

Description

technical field [0001] The present invention relates to a pixel structure and a display panel, and in particular to a pixel structure that helps to improve light transmittance and a display panel using the pixel structure. Background technique [0002] Currently, the performance requirements of the market for LCD panels include high contrast ratio, no gray scale inversion, low color shift, high luminance, and high color saturation. , quick response and wide viewing angle. At present, the technologies that can meet the requirement of wide viewing angle include Twisted Nematic (TN) liquid crystal with wide viewing film (wide viewing film), in-plane switching (In-Plane Switching, IPS) liquid crystal display panel, marginal field switching Type (Fringe Field Switching) liquid crystal display panel, multi-domain vertical alignment (Multi-domain Vertical Alignment, MVA) liquid crystal display panel, etc. [0003] In the existing multi-domain vertical alignment liquid crystal dis...
