1. A display substrate, comprising:
a base substrate comprising at least a pixel area and a hole area;
a plurality of sub-pixels on the base substrate, wherein the plurality of sub-pixels are located in the pixel area;
a hole in the hole area;
a first barrier dam arranged between the sub-pixels and the hole and at least partially surrounding the hole;
a functional film layer arranged on the base substrate;
an organic material layer arranged on a side of the functional film layer away from the base substrate, wherein an orthographic projection of the organic material layer on the base substrate falls within the pixel area, and the organic material layer comprises at least one film layer;
an encapsulating structure arranged on a side of the organic material layer away from the base substrate; and
a filling structure, wherein at least a portion of the filling structure is arranged between the hole and the first barrier dam,
wherein the filling structure and the at least one film layer of the organic material layer are located in the same layer and comprise the same material.
