Claim 12:
13. The display substrate according to claim 11, further comprising:
a semiconductor layer, located on the base substrate, and located on a side of the first source-drain metal layer close to the base substrate;
a first gate electrode layer, located on a side of the semiconductor layer away from the base substrate, and
a second gate electrode layer, located between the first gate electrode layer and the first source-drain metal layer,
wherein the first gate electrode layer comprises an emission control line extending in the first direction, and the orthographic projection of the spacer on the base substrate is overlapped with an orthographic projection of the emission control line on the base substrate.
