Claim 11:
12. The display substrate according to claim 11, wherein the pixel driving circuit further includes:
a seventh transistor including:
a seventh active pattern having a seventh channel region, and a thirteenth doped region and a fourteenth doped region that are located on two opposite sides of the seventh channel region; and a portion of the seventh active pattern located in the fourteenth doped region and a portion of the fourth active pattern located in the eighth doped region being connected as a whole; and
a seventh gate, an orthographic projection of the seventh gate on the base overlapping with an orthographic projection of the seventh channel region on the base; and

a fourth auxiliary pattern disposed in a same layer as the third auxiliary pattern; the fourth auxiliary pattern being electrically connected to a portion of the seventh active pattern located in the thirteenth doped region through a ninth via penetrating the insulating layer, and being electrically connected to an initialization signal line corresponding to a next row of pixel driving circuits adjacent to the pixel driving circuit through a tenth via penetrating the third insulating sub-layer.
