Abstract: There is provided a display substrate, a manufacturing method thereof, and a display device, relating to the field of display technology. The display substrate includes: a base substrate; a self-luminescent layer disposed on a side of the base substrate; and an encapsulation film layer disposed on a side of the self-luminescent layer away from the base substrate. The display substrate has a gap, which penetrates through the self-luminescent layer and the encapsulation film layer, and separates the self-luminescent layer and the encapsulation film layer into at least two parts with a part corresponding to a to-be-perforated area of the display substrate and another part corresponds to a non-perforated area of the display substrate other than the to-be-perforated area. The edge of the encapsulation film layer adjacent to the gap covers the side surface of the edge of the self-luminescent layer adjacent to the gap.
