Abstract
Provided are an array substrate and a manufacturing method therefor, a display panel, and a display device. The array substrate includes: a plurality of electrodes arranged in an array. The electrode includes a plurality of strip electrodes that are connected to each other and spaced. The plurality of strip electrodes at least have two thicknesses. A distance between two adjacent strip electrodes is less than a preset value. During manufacturing, a mask used for forming each layer of sub-electrodes includes a plurality of strip-shaped shading regions that are connected to each other and spaced in a first direction. Strip-shaped shading regions in a mask used for sub-electrodes formed subsequently are integrally shifted by a first distance in the first direction relative to strip-shaped shading regions in a mask used for sub-electrodes formed last time.
