Claim 2:
3. The display substrate according to claim 1, further comprising:
a plurality of first voltage lines disposed on the base and located in the display area; the plurality of first voltage lines all extending in the first direction; and the plurality of first voltage lines and the plurality of data lines being disposed in a same layer; wherein
the pixel driving circuit further includes a second transistor, and the second transistor includes:
a second active pattern having a second channel region, and a third doped region and a fourth doped region that are located on two opposite sides of the second channel region; and a portion of the second active pattern located in the fourth doped region and a portion of the first active pattern located in the second doped region being connected as a whole;
a second gate, an orthographic projection of the second gate on the base overlapping with an orthographic projection of the second channel region on the base; and
a second insulating block, the second insulating block being a portion of the insulating layer in a region where the second transistor is located, and the second insulating block having a second via; a first voltage line connected to the column of pixel driving circuits being electrically connected to a portion of the second active pattern located in the third doped region through the second via;

wherein sizes of all second vias in the column of pixel driving circuits gradually increase in the first direction.
