Abstract
This application provides a display substrate, a method for manufacturing the same, and a display device, which belongs to the technical field of displays. The method for manufacturing the display substrate comprises: forming a metal layer on a base substrate; forming a photoresist layer on the metal layer; exposing the photoresist layer by using a mask plate; developing the exposed photoresist layer to form a photoresist pattern; and omitting a step of baking the photoresist pattern, and etching the metal layer by using the photoresist pattern as a mask to form a signal line. The technical solution of the present disclosure can realize a narrow frame of a display product.
