Display substrate, method for manufacturing same, and display apparatus

A method for manufacturing a display substrate, wherein the display substrate comprises a display area, a barrier wall disposing area, and a hole area, the display area surrounds the barrier wall disposing area, the barrier wall disposing area surrounds the hole area, and the method comprises:

• removing, after a first electrode of a light emitting device of the display substrate is formed, a protective layer of the barrier wall disposing area, and exposing at least one circle of an initial barrier wall covered by the protective layer, wherein the initial barrier wall is disposed around the hole area;
• and
• etching the at least one circle of the initial barrier wall, to form at least one circle of a barrier wall, wherein a notch is formed on at least one side surface of the barrier wall;
• wherein the removing a protective layer of the barrier wall disposing area comprises:
• coating a photoresist on the display substrate on which the first electrode is formed, and exposing the photoresist by using a mask, wherein the mask comprises a translucent pattern corresponding to the barrier wall disposing area;
• removing the photoresist of the barrier wall disposing area after development;
• and
• performing dry etching on the protective layer of the barrier wall disposing area by using a remaining photoresist as a mask, removing the protective layer of the barrier wall disposing area, and exposing the initial barrier wall.
