Pixel unit and array substrate

Abstract

The invention discloses a pixel unit and an array substrate. A pixel unit includes a scan line, a data line, a welding pad, an insulating layer and several strip electrodes. The scanning lines extend along a first extending direction, the data lines extend along a second extending direction, and the first extending direction intersects with the second extending direction. The welding pad is formed at the intersection of the scanning line and the data line, and is electrically connected with the scanning line and the data line. The insulating layer covers the scanning lines and the data lines, and the insulating layer is provided with via holes. A plurality of strip-shaped electrodes are arranged parallel to each other and at intervals. The strip-shaped electrodes are arranged on the insulating layer and extend along the third extension direction. The third extension direction forms a predetermined angle with the first extension direction. sexual connection. Both the pad and the strip electrode are made of transparent conductive material, the pad is polygonal, and at least one side of the pad is parallel to the third extension direction. The implementation of the present invention can reduce the influence of the electric field of the strip electrode and effectively suppress the phenomenon of "dark stripes" around the welding pad.

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 (LiquidCrystalDisplay, liquid crystal display) is the current mainstream display technology. The liquid crystal display device includes a pair of substrates and a liquid crystal layer sandwiched 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 display...

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 (IndiumTinOxide, indium oxide tin), therefore, the pad 110 will also generate an electric field when electrified. 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 Liquid crystal molecules are disordered
