1. A display substrate, comprising:
a base substrate, the base substrate comprising a display region and an opening region adjacent to each other; and
at least one isolation wall extending along a boundary between the display region and the opening region;
wherein each of the at least one isolation wall comprises at least one isolation structure, and each of the at least one isolation structure comprises:
a first layer on a side of the base substrate; and
a second layer on a side of the first layer away from the base substrate;
and wherein an orthographic projection of the first layer on the base substrate is within an orthographic projection of the second layer on the base substrate, and the first layer and the second layer are inorganic dielectric layers.
