1. A display substrate, comprising a base substrate and a pixel definition layer arranged on the base substrate, wherein
the pixel definition layer comprises a first film layer and a second film layer, the first film layer is arranged at a side of the second film layer adjacent to the base substrate, and an orthogonal projection of a top surface of the first film layer onto the base substrate completely falls within an orthogonal projection of a bottom surface of the second film layer onto the base substrate,
wherein the first film layer comprises a first dam member and a second dam member, the second dam member is arranged at a side of the first dam member away from the base substrate,
wherein the second film layer comprises a third dam member, an orthogonal projection of a top surface of the second dam member onto the base substrate completely falls within an orthogonal projection of a bottom surface of the third dam member onto the base substrate, and an edge of the orthogonal projection of the top surface of the second dam member onto the base substrate is spaced apart by a certain distance from an edge of the orthogonal projection of the bottom surface of the third dam member onto the base substrate.
