Pixel array substrate, liquid crystal display device and driving method thereof

Abstract

The invention discloses a pixel array substrate, a liquid crystal display (LCD) device and a driving method thereof. The pixel array substrate is provided with a plurality of pixel regions, a black matrix, a plurality of first pixel electrodes and a plurality of second pixel electrodes, wherein each pixel region is divided into three pixel subregions; the black matrix is provided with a plurality of openings, and each opening exposes one pixel region; each first pixel electrode is arranged in one pixel subregion between every two pixel subregions in each pixel region, and the first pixel electrodes are arranged in an intersected shape; the second pixel electrodes are provided with two half intersected parts and a connecting branch for connecting with the two half intersected parts; the two half intersected parts are respectively arranged in the two pixel subregions at the two sides of each pixel region; and the trunk of the edge in parallel to the opening in the half intersected part overlaps the black matrix. The invention can solve the defects of reduced luminance, reduced contrast ratio and striped picture caused by the traditional low color cast design.

Description

technical field [0001] The invention relates to a pixel array substrate, a liquid crystal display device and a driving method thereof, and in particular to a pixel array substrate with low color shift, a liquid crystal display device and a driving method thereof. Background technique [0002] At present, the performance requirements of the market for liquid crystal display devices are towards high contrast (high contrastratio), no gray scale inversion (no gray scale inversion), low color shift (low color shift), high brightness (high luminance), high color richness High-resolution, high color saturation, fast response and wide viewing angle. At present, the technologies that can meet the requirement of wide viewing angle include twisted nematic (TN) liquid crystal plus wide viewing film (wide viewing film), in-plane switching (IPS) liquid crystal display device, fringe field A fringe field switching liquid crystal display device, a multi-domain vertical alignment (MVA) liqu...
