A display substrate includes a plurality of data lines and a plurality of columns of pixel driving circuits. A column of pixel driving circuits is connected to a corresponding data line, and each pixel driving circuit includes a driving transistor and a first transistor. The driving transistor is a P-type transistor. The first transistor includes: a first active pattern having a first channel region, and a first doped region and a second doped region on two opposite sides of the first channel region; a first gate; and a first insulating block disposed on a side of the first active pattern away from the base and having a first via. The data line is connected to a portion of the first active pattern located in the first doped region through the first via. Sizes of all first vias in the column of pixel driving circuits gradually decrease in a first direction.
