Abstract
The present disclosure provides a display substrate, a display panel and a display device. The display substrate includes a base substrate and at least one layer formed on the base substrate, and the layer is formed with an alignment mark, which includes a dot array composed of a plurality of dots. With such dot array composed of the plurality of dots, a step or height difference between the alignment mark and portions of the layer around the alignment mark can be reduced, and adverse influence on the rubbing alignment caused by alignment mark can be reduced or eliminated, thereby reducing or eliminating rubbing Mura in the region where the alignment mark is located.
