Claim 8:
9. The display substrate according to claim 7, wherein the pixel driving circuit further includes:
at least one fifth transistor, each fifth transistor including:
a fifth active pattern having a fifth channel region, and a ninth doped region and a tenth doped region that are located on two opposite sides of the fifth channel region; and
a fifth gate, an orthographic projection of the fifth gate on the base overlapping with an orthographic projection of the fifth channel region on the base;
wherein a portion of the fifth active pattern in the at least one fifth transistor located in the ninth doped region and a portion of the third active pattern located in the driving transistor located in the sixth doped region are connected as a whole; and

a second auxiliary pattern disposed in a same layer as the first auxiliary pattern; the second auxiliary pattern being electrically connected to the first storage electrode through a fifth via penetrating the third insulating sub-layer and the second insulating sub-layer, and being electrically connected to a portion of the fifth active pattern located in the tenth doped region through a sixth via penetrating the insulating layer.
