Pixel electrode and liquid crystal display (LCD) panel

Abstract

A pixel electrode (100) and a liquid crystal panel. The pixel electrode (100) is provided thereon with at least one slit (10) which tilts relative to an edge of the pixel electrode (100). Two ends of the slit (10) extend to the edge of the pixel electrode (100). Two sides of the slit (10) are provided with a plurality of equal cuts (11) with the same depth. Two sides of each of two end regions of the slit (10) have a plurality of edge cuts (13) the bottoms of which extend to the edge of the pixel electrode (100). The end regions of the slit (10) are also provided with a plurality of gradient cuts (12) the depths of which decrease gradually in a direction from the outside of the pixel electrode (100) to the inside. The depth of the gradient cut (12) is greater than or equal to that of the equal cut (11). By changing the depth of the upper edge cut (13) of the pixel electrode (100), mitigating the anomalous electric field among the cuts and at the end portions of the cuts on the extension structure of a common electrode (200) and at the same time forming a gradient cut (12) on one side of the edge cut (13) to enable the electric field at the edge to gradually transit to the electric field inside the pixel, the liquid crystal molecules in this region are prevented from being arranged anomalously, reducing the generation of dark fringes here, thus improving the penetration rate of the pixel.

Description

technical field [0001] The invention relates to the field of liquid crystal display, and more specifically, relates to a pixel electrode and a liquid crystal panel. Background technique [0002] Liquid crystal display devices have been widely used in human life and work, and the liquid crystal panel of the liquid crystal display device is related to the display effect of the liquid crystal display device, including viewing angle, brightness, and color. [0003] Such as figure 1 Shown is a situation where the common electrode 200 overlaps with the pixel electrode 100 in a pixel area of ​​an existing liquid crystal panel, wherein, as image 3 As shown, the pixel electrode 100 is provided with two symmetrical slits 10 that are inclined relative to the edge of the pixel electrode 100, and the two ends of the slit 10 extend to the edge of the pixel electrode 100; The side is provided with a plurality of equal cuts 11 with the same depth; as figure 1 As shown, the junction of t...

Problems solved by technology

To solve this problem, a slit is often added to the side edge of the common electrode 200, such as figure 2 Taking the second junction 2 as an example, an extension structure 210 is provided at the border junction of the common electrode 200 and the pixel electrode 100, and a wing-shaped slit pattern is formed on the extension structure 210. The structure 210 forms cutouts at the edge to alleviate the influence of the fringe field effect on the liquid crystal molecules; however, the electric field between the cutouts and at the ends of the cutouts is still different from the internal electric field of the pixel, resulting in abnormal alignment of the liquid crystal molecules (disclination) ,like figure 1 As shown, there is still abnormal arrangement of liquid crystal molecules (disclination) at the first junction 1, the second junction 2, the third junction 3 and the fourth junction 4, which reduces the transmittance of these four places, and thus makes the entire pixel The penetration rate is reduced
