Problems solved by technology

[0002] At present, the pixel structure of thin film transistor liquid crystal display (TFT-LCD) can improve the color shift through the self-compensation of liquid crystal, but the effect of expanding the viewing angle is limited, and it still cannot effectively expand the viewing angle in different directions.
Moreover, in the traditional pixel structure, the gate / source parasitic capacitance is easy to change with the deviation of the process, which leads to different jump voltages in different display areas, and the screen may have adverse effects such as flickering or image sticking. product quality

Abstract

Provided are a pixel unit and an array substrate comprising the pixel unit, and a liquid crystal display device. The pixel unit comprises a scanning line (6), a signal line (1), a slit electrode (4), a coupling electrode (3) capable of cooperatively forming an electric field with the slit electrode (4), and a thin-film transistor, wherein a plurality of slits are formed on the slit electrode (4), the scanning line (6) and the signal line (1) are arranged crosswise and limit at least two sub-regions (I, II, III, IV). The coupling electrode (3) comprises at least two sub-electrodes respectively located in one of the sub-regions (I, II, III, IV). The slit electrode (4) corresponds to all the sub-regions (I, II, III, IV) and the extension directions of the slits located in different sub-regions (I, II, III, IV) are different. Therefore, enlarging the visual angles of different directions can effectively eliminate colour cast, and the aperture ratio can be effectively improved, thereby significantly improving the display quality.
