Display substrate, method for manufacturing the same, and display device

Abstract

A display substrate, a method for manufacturing the display substrate and a display device are provided in this disclosure. The display substrate includes a substrate film layer and functional film layers, the display substrate includes a display region and a hole-forming region, and the method includes: forming a plurality of functional film layers on the substrate film layer; etching at least one of the functional film layers in the hole-forming region to form a first via-hole penetrating the at least one of the functional film layers; forming a transition layer that covers the display region and reveals the first via-hole; forming a second via-hole in the hole-forming region by using the transition layer as a mask, the second via-hole penetrating the substrate film layer and all the functional film layers apart from the at least one of the functional film layers; and removing the transition layer.
