1. A display substrate, comprising: a base substrate and a drive circuit layer arranged on the base substrate, wherein the base substrate comprises a display region and a non-display region, and the drive circuit layer comprises a pixel drive circuit located in the display region, a gate drive circuit located in the non-display region, and at least one initial power supply line which extends at least partially along a first direction;
the gate drive circuit is configured to provide a drive signal to the pixel drive circuit, and the initial power supply line is configured to provide an initial signal to the pixel drive circuit, wherein at least one gate drive circuit is located on at least one side of the display region respectively;
an orthographic projection of at least one of the at least one initial power supply line on the base substrate is at least partially overlapped with an orthographic projection of the gate drive circuit on the base substrate;
wherein one of the at least one gate drive circuit on one side of the display region comprises: a plurality of drive circuits arranged along a second direction; and the at least one initial power supply line comprises: a first initial power supply line to an N-th initial power supply line, wherein the first direction intersects with the second direction, and N is a positive integer greater than or equal to 2; and
the N initial power supply lines are arranged along the second direction, and an orthographic projection of K adjacent initial power supply lines away from the display region on the base substrate is at least partially overlapped with an orthographic projection of a drive circuit, close to the display region, of the plurality of drive circuits on the side of the display region on the base substrate, wherein K is a positive integer less than or equal to N.
