Embodiment 1

[0042]In the pixel electrode structures provided in the first and second embodiments, each bent branch 3 of the branch portion is composed of two branches, and each branch has a different angle with the horizontal trunk 1 . Of course, according to the principles of the present invention, each bent-shaped branch 3 of the branch portion may also be composed of more segments of branches, see the following embodiments.

[0043] see Figure 4 , Figure 4 It is a schematic structural diagram of the third embodiment of the pixel electrode structure of the present invention.

[0044] In the pixel electrode structure provided in the embodiment of the present invention, in each of the bent branches 3, the branch closest to the center point of the vertical intersection of the horizontal trunk 1 and the vertical trunk 2 is branched to the farthest branch with the horizontal The angle of the included angle formed by the trunk 1 may increase from small to large.

Abstract

The invention provides a pixel electrode structure, comprising a main part and a branch part, wherein the main part is composed of two partial pixel electrode regions, namely a horizontal main part and a vertical main part which are vertically intersected in the center; the branch part is composed of four parts of pixel electrode regions equally divided by the horizontal main part and the vertical main part which are vertically intersected in the center; a plurality of buckling linear branches are arranged in each part of the pixel electrode regions of the branch part, each buckling linear branch is composed of multiple branches, and angles of included angles formed by every two adjacent branches and the horizontal main part are different; and gaps are kept between every two buckling linear branches. By applying the pixel electrode structure provided by the invention, the technical problems that vision colour shift is caused and penetration rate is reduced as an included angle between a strip branch in the branch part and the horizontal main part is the same as the included angle between the strip branch in the branch part and the vertical main part in the prior art can be effectively solved.

Description

technical field [0001] The present invention relates to the technical field of liquid crystal display, in particular to a pixel electrode structure of a liquid crystal display. Background technique [0002] Liquid Crystal Display (LCD, Liquid Crystal Display) is one of the most widely used flat panel displays, LCD includes a pair of panels provided with field generating electrodes such as pixel electrodes and common electrodes, and a liquid crystal (LC, Liquid) provided between the two panels. Crystal) layer. When a voltage is applied to the field generating electrode to generate an electric field in the LC layer, the electric field determines the orientation of the LC molecules in the liquid crystal layer, thereby adjusting the polarization of light incident on the liquid crystal layer, so that the LCD displays images. [0003] At present, a technology called Polymer Stabilized Vertical Alignment (PSVA) has been developed in the industry. This technology is to mix a suitab...
