Array substrate, display panel, and display device

Abstract

The disclosure discloses an array substrate, a display panel, and a display device. The array substrate comprises a first substrate, a first common electrode line, a second common electrode line, anda plurality of third common electrode line, wherein the first common electrode line, the second common electrode line, and the plurality of third common electrode line are arranged on the first substrate. One end of the first common electrode line is connected to one end of each of the plurality of third common electrode lines and the other end of the first common electrode line is connected to the other end of each of the plurality of third common electrode lines. The first common electrode line and the second common electrode line are connected; and the third common electrode lines are broken at the intersection parts with the second common electrode line. Therefore, the connection of the third common electrode lines with the second common electrode line is avoided; the light leakage atthe junctions of the third common electrode lines and the second common electrode line is improved; and the contrast of the display panel is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to an array substrate, a display panel and a display device. Background technique [0002] With the development of science and technology and the progress of society, liquid crystal displays have been more and more widely used by people, and play a vital role in industrial production and people's lives; at present, high-quality liquid crystal displays are more and more popular among people. Favored, many companies in the field of display technology have invested huge manpower and material resources in the direction of high contrast, fast response and low power consumption. [0003] The inventors of the present application have discovered in long-term research and development that the corners of the metal traces on the array substrate on the mask are all 90° right angles, but after the actual exposure, development and etching processes, the right angles will become constan...

Problems solved by technology

[0003] The inventors of the present application have discovered in long-term research and development that the corners of the metal traces on the array substrate on the mask are all 90° right angles, but after the actual exposure, development and etching processes, the right angles will become constant. The curved shape of the metal line will cause obvious light leakage in the corner area of ​​the metal trace, which will affect the contrast of the display panel and make the quality of the display panel poor.
