Claim 0:
1. A display substrate, the display substrate comprising a display area and a frame area, the display substrate comprising:
a substrate;
a plurality of sub-pixels on a side of the substrate, the plurality of sub-pixels configured to emit light in the display area;
an encapsulation layer on a side of the plurality of sub-pixels away from the substrate; and
a retaining wall in the frame area, wherein the retaining wall is between the encapsulation layer and the substrate and comprises a first sub-retaining wall, a second sub-retaining wall, and a transition area between the first sub-retaining wall and the second sub-retaining wall,
wherein the second sub-retaining wall is on a side of the first sub-retaining wall away from the display area, a vertical distance between an end of the second sub-retaining wall away from the substrate and the substrate is greater than the vertical distance between an end of the first sub-retaining wall away from the substrate and the substrate, the vertical distance between the end of the first sub-retaining wall away from the substrate and the substrate is greater than a vertical distance between and end of the transition area away from the substrate and the substrate; and
wherein, the retaining wall comprises at least one layer provided in a same layer, the at least one layer provided in the same layer continuously extends across the first sub-retaining wall, the second sub-retaining wall and the transition area.
