Problems solved by technology
[0003] In the existing ADS type display device, due to the large overlapping area and small spacing between the pixel electrode and the common electrode, the storage capacitor Cst is very large, so there are many restrictions on design.
At present, in order to solve the problem of too large Cst, pixel electrodes and common electrodes are usually arranged in a staggered manner, but in general, since the pixel electrodes and common electrodes are made of transparent electrode materials, the staggered arrangement requires precise exposure process This will undoubtedly increase the difficulty and cost of equipment and process control

Description
technical field [0001] The invention relates to the field of liquid crystal displays, in particular to an array substrate, a manufacturing method thereof, and a display device. Background technique [0002] Common liquid crystal display devices in the prior art mainly include AD-SDS (Advanced-Super Dimensional Switching, referred to as ADS, advanced super-dimensional field switch) type, IPS (In Plane Switch, transverse electric field effect) type and TN (Twist Nematic, twisted nematic) type. Among them, the ADS type display device forms a multi-dimensional electric field through the parallel electric field generated by the edge of the pixel electrode in the same plane and the vertical electric field generated between the pixel electrode layer and the common electrode layer, so that all the alignment liquid crystal molecules between the pixel electrodes and directly above the electrodes in the liquid crystal cell Both can generate rotation transformations. [0003] In the e...
