Abstract
A display substrate and a manufacturing method thereof, and a display device are provided. The display substrate includes a base substrate, including a pixel array region and a peripheral region; and a first scan driving circuit, a plurality of power lines, a first signal line group, and a second signal line group. The first scan driving circuit includes a plurality of cascaded first shift registers; the plurality of power lines are configured to provide a plurality of power voltages to the plurality of cascaded first shift registers in the first scan driving circuit; the first signal line group includes at least one timing signal line; the second signal line group includes a first trigger signal line configured to provide a first trigger signal to a first-stage first shift register; and the first trigger signal line is between the plurality of power lines and the pixel array region.
