Abstract

A display substrate includes a substrate, at least one inorganic film, metal film(s) and organic film(s), the at least one inorganic film is disposed on the substrate; at least one edge portion of the entire at least one inorganic film is step-shaped. The metal film(s) are disposed on a side of the at least one inorganic film facing away from the substrate. A metal film includes a conductive pattern and residual pattern(s), and an orthographic projection of a residual pattern on the substrate is located within an orthographic projection of a step-shaped edge portion of the at least one inorganic film on the substrate. An organic film is disposed on a side of the metal film facing away from the substrate, and an edge portion of the organic film covers the residual pattern of the metal film.
