Pixel unit and array substrate

Abstract

The invention discloses a pixel unit and an array substrate. The pixel unit comprises a scanning line, a data line, a welding disk, an insulating layer and a plurality of strip-shaped electrodes, wherein the scanning line extends in the first extension direction, the data line extends in the second extension direction, and the first extension direction intersects with the second extension direction. The welding disk is formed in the intersected position of the scanning line and the data line and electrically connected with the scanning line and the data line. The insulating layer covers the scanning line and the data line and is provided with via holes. The strip-shaped electrodes are mutually parallel and arranged at intervals, the strip-shaped electrodes are arranged on the insulating layer and extend in the third extension direction, a predetermined angle is formed between the third extension direction and the first extension direction, and the strip-shaped electrodes are electrically connected with the welding disk through the via holes. The welding disk and the strip-shaped electrodes are made of transparent conductive material, the welding disk is in the shape of a polygon, and at least one side of the welding disk is parallel to the third extension direction. According to the pixel unit and the array substrate, effects on an electric field of the strip-shaped electrodes can be reduced, and the phenomenon of 'dark fringes' around the welding disk can be effectively restrained.

Description

technical field [0001] The present invention relates to the technical field of liquid crystal display, in particular to a pixel unit, and also to an array substrate. Background technique [0002] LCD (Liquid Crystal Display, Liquid Crystal Display) is currently the mainstream display technology. The liquid crystal display device includes a pair of substrates and a liquid crystal layer interposed between the pair of substrates, and electric field generating electrodes, such as pixel electrodes and common electrodes, are respectively arranged on the two substrates. Applying a voltage on the two substrates will generate an electric field in the liquid crystal layer, and the direction of the electric field determines the alignment direction of the liquid crystal molecules. By adjusting the voltage, the arrangement direction of the liquid crystal molecules is changed, so that the light incident into the liquid crystal layer is polarized, and the liquid crystal display device dis...

Problems solved by technology

[0004] In the prior art, it is only considered that the electric field generated by the strip electrodes 120 will affect the alignment of liquid crystal molecules. However, since the pads 110 and the strip electrodes 120 are made of transparent conductive materials, such as ITO (Indium Tin Oxide, Indium tin oxide), therefore, the pad 110 will also generate an electric field when energized, since the edge of the pad 110 crosses the direction of the strip electrode 120, the electric field generated by the edge of the pad 110 will affect the electric field of the strip electrode 120 , resulting in disordered arrangement of liquid crystal molecules
