Liquid crystal display device

Abstract

The invention discloses a liquid crystal display device which comprises an upper substrate, a lower substrate and liquid crystal molecules, wherein the liquid crystal molecules are clamped between the upper substrate and the lower substrate. The upper substrate and the lower substrate are provided with a plurality of opposite pixel areas, each pixel area of the lower substrate is provided with a common electrode and a pixel electrode, each pixel electrode comprises a plurality of linear slits, the upper substrate comprises first black matrixes, second black matrixes and color layers, the second black matrixes are perpendicular to the first black matrixes, the color layers are positioned among the first black matrixes, the second black matrixes penetrate middle of each color layer, each color layer is divided into two sub color layers, the pixel areas are divided into upper semi-domains and lower semi-domains by the second black matrixes, and alignment directions of the liquid crystal molecules in the upper semi-domains and the lower semi-domains are symmetrical. According to the liquid crystal display device, shapes and alignment directions of the electrodes are changed, so that whole area electric fields of the electrodes are uniform, and dark fringes can be improved.

Description

Technical field [0001] The invention belongs to the technical field of liquid crystal display, and particularly relates to a liquid crystal display device capable of improving dark lines. Background technique [0002] FFS (Fringe Field Switching) technology belongs to the wide viewing angle technology of LCD panels. The wide viewing angle technology is mainly used to make the viewing angle of the panel wider and also contribute to the performance of other characteristics such as image quality and brightness. Traditional FFS pixels generally have a dual-domain structure. The electrodes have certain corners in the middle and the extreme ends, and the alignment angle is along one direction. The alignment method is rubbing or optical alignment. [0003] Such as figure 1 As shown, a common FFS display device includes an upper substrate and a lower substrate. The lower substrate is provided with a common electrode and a pixel electrode. The pixel electrode is a dart type with a certain c...

AI Technical Summary

Problems solved by technology

[0004] The distribution of traditional FFS electrodes leads to a strong electric field strength along the middle part of the pixel to the electrode extension direction, and a weak electric field from the outer part of the electrode to the edge part, so dark lines are prone to appear
