Claim 11:
12. The display substrate according to claim 10, further comprising:
a pixel defining layer located at a side of the second electrode of each sub-pixel away from the base substrate, wherein the pixel defining layer comprises an opening for defining a light emitting region of each sub-pixel, at least part of the organic light emitting layer of each sub-pixel is located in the opening, and an orthographic projection of the opening of the pixel defining layer on the base substrate is located in an orthographic projection of the main electrode of the second electrode of each sub-pixel on the base substrate;
in the pixel defining layer, an area of an opening defining a light emitting region of each third color sub-pixel is greater than an area of an opening defining a light emitting region of each second color sub-pixel and smaller than an area of an opening defining a light emitting region of each first color sub-pixel.
