Abstract

The invention provides a pixel unit and a liquid crystal display device. The pixel unit comprises four sub-pixel units, each sub-pixel unit comprises a pixel electrode, the pixel electrode comprises aplurality of strip-shaped parts which are distributed at intervals, and a slit is defined between every two adjacent strip-shaped parts; each strip-shaped part and the slit adjacent to the strip-shaped part are defined as an electrode part, the width of the electrode part is the sum of the widths of the strip-shaped part and the slit, wherein the width of each electrode part and / or the width of each strip-shaped part and / or the width of each slit are / is different, so that penetration rate-voltage curves of the pixel electrode at different positions are different, the visual angle difference problem of the four-domain pixel electrode can be improved, and the display quality of the liquid crystal display device is further improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a pixel unit and a liquid crystal display device. Background technique [0002] Due to the small pixel size of 8K liquid crystal displays, in order to improve the transmittance of pixels, 4-domain pixel electrode design is usually used at present. The widths of the 8K LCDs are all the same, which leads to the problem of large viewing angle deviation, which seriously affects the picture quality of the 8K LCD, and becomes one of the key factors restricting the further development of the 8K LCD. [0003] To sum up, it is necessary to provide a new pixel unit and a liquid crystal display device to solve the above technical problems. Contents of the invention [0004] The pixel unit and the liquid crystal display device provided by the present invention solve the technical problem that the width of the strip portion at each position and the width of the slit at each position of th...
