Array substrate and display panel

Abstract

The invention provides an array substrate and a display panel. The array substrate comprises a substrate, a first metal layer, an active material layer, a second metal layer, a pixel electrode layer and a common electrode layer, the first metal layer comprises a gate layer of the switching element, a scanning line connected with the gate layer and a shielding metal layer. The shielding metal layercomprises a plurality of shielding metal wires; at least one opening is formed in at least one joint through the two shielding metal wires. Therefore, each shielding metal wire is designed in a circular ring non-closed manner. Therefore, at least one outer corner arranged opposite to the pixel electrode layer is formed at the opening by the overlapped part of the shielding metal wire and the pixel opening area; and the convex parts are arranged at the outer corners and are used for compensating the outer corners which cannot form ideal right angles due to processing factors into right angles,so that dark-state light leakage points can be reduced, the light leakage condition can be improved, and the contrast ratio of a display picture can be improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate and a display panel. Background technique [0002] Contrast is an important parameter of the display, which can vividly display the difference between the bright and dark states of the picture. Since the liquid crystal display cannot emit light by itself, it often needs an additional backlight to provide brightness. In the dark state, the liquid crystal is affected by irregular electric fields or topography. The brightness of the position backlight will be received by the human eye through the liquid crystal layer, resulting in an increase in the brightness of the dark state and affecting the viewing effect. [0003] Usually, there are a variety of opaque metal traces in the array substrate. The corners of the metal traces often cannot form an ideal right angle due to process factors. The metal traces are not perpendicular or parallel to the polarizer,...

AI Technical Summary

Problems solved by technology

[0005] The array substrate and display panel provided by the present invention solve the problem of the existing array substrate and display panel. When the shielding metal wiring adopts a circular closed design, since the four existing metal intersections are all inner corners, and the mask compensation The effect of the inner corner is not obvious, which leads to serious light leakage and poor contrast in the dark state.
