Claim 8:
9. The display substrate according to claim 3, wherein the sub-pixel driving circuit further includes: a third conductive connection portion;
there is a sixth overlapping area between an orthographic projection of the third conductive connection portion to the base substrate and an orthographic projection of the first conductive connection portion to the base substrate; the third conductive connection portion is coupled to the first conductive connection portion through a fourth via hole in the sixth overlapping area;
each of the plurality of sub-pixels further includes a light-emitting unit disposed at one side of the sub-pixel driving circuit away from the base substrate; the light-emitting unit includes an anode, a light-emitting layer and a cathode, which are sequentially stacked in a direction away from the base substrate;
there is a seventh overlapping area between an orthographic projection of the anode to the base substrate and an orthographic projection of the third conductive connection portion to the base substrate; the anode is coupled to the third conductive connection portion through a fifth via hole in the seventh overlapping area.
