1. A display substrate, which comprises a display region and a bonding region located on one side of the display region, the display region at least comprising a first wiring region and a second wiring region, wherein
the first wiring region is provided with at least one first wiring and at least one light emitting device, the second wiring region is provided with at least one second wiring and at least one light emitting device, and the at least one light emitting device in the first region and the at least one light emitting device in the second region both comprise an anode;
a first terminal of the at least one first wiring is connected with a bonding lead line of the bonding region, a second terminal of the at least one first wiring is connected with a first terminal of the at least one second wiring after extending along a second direction, and a second terminal of the at least one second wiring is connected with data signal line of the display region after extending along a first direction, wherein the first direction crosses the second direction; and
the first wiring region further comprises at least one first compensation line extending along the first direction, an orthographic projection of at least one anode in a plane of the display substrate overlaps at least partially with an orthographic projection of the at least one first compensation line in the plane of the display substrate, and/or, the second wiring region further comprises at least one second compensation line extending along the second direction, and an orthographic projection of at least one anode in the plane of the display substrate overlaps at least partially with an orthographic projection of the at least one second compensation line in the plane of the display substrate.
