Problems solved by technology
[0003] In the prior art, static electricity is often generated during the manufacture of display panels. When the electrostatic charge accumulates to a certain extent, it may cause electrostatic breakdown (Electrostatic Discharge, ESD), which will adversely affect the performance of the device.
Especially in the manufacture of array substrates, there is a large area of dummy metal lines between two ICs, which is prone to electrostatic breakdown in the pixel area (occurrence rate 3% to 4%)

The invention relates to the field of displaying, and provides an array substrate, a manufacturing method thereof, a display panel and a display device. The manufacturing method of the array substratecomprises the steps of supplying the array substrate which is provided with a pixel region and a fan-out region; forming a first wiring region, a second wiring region and a suspended region between the first wiring region and the second wiring region in the fan-out region, and connecting the fan-out region with the pixel region; forming a film virtual metal wire in the suspended region; and patterning the film virtual metal wire. Through patterning the film virtual metal wire, accumulated static charges are reduced for preventing static breakdown; and on the other hand, Rubbing Mura in friction orientation of an alignment film is prevented, thereby improving product performance. Furthermore simple operation is realized in removing the film virtual metal wire according to the method. The number of processing procedures of the array substrate and manufacturing cost are reduced.
Description
technical field [0001] The present disclosure relates to the display field, and in particular to an array substrate, a method for manufacturing the array substrate, a display panel including the array substrate, and a display device. Background technique [0002] In recent years, the development trend of displays has gradually developed towards the direction of high integration and low cost. From the initial CRT (Cathode Ray Tube, cathode ray tube) display to the now commonly used liquid crystal display, its integration, manufacturing cost, and picture quality The average has been greatly improved. [0003] In the prior art, static electricity is often generated during the manufacture of display panels. When the electrostatic charge accumulates to a certain extent, it may cause electrostatic breakdown (Electrostatic Discharge, ESD), which will adversely affect the performance of the device. Especially when manufacturing the array substrate, there is a large-area dummy metal...
