Abstract

A display substrate is provided, including: a base substrate including at least pixel and hole areas; sub-pixels arranged on the base substrate and in the pixel area; a hole in the hole area; a first barrier dam between the sub-pixels and the hole and at least partially surrounding the hole; a functional film layer, an organic material layer and an encapsulating structure sequentially arranged on the display substrate in a direction away from the base substrate, an orthographic projection of the organic material layer on the base substrate falling within the pixel area, the organic material layer including at least one film layer; and a filling structure, at least a portion of which is arranged between the hole and the first barrier dam. The filling structure and the at least one film layer of the organic material layer are in the same layer and include the same material.
