1. A display substrate, comprising a first voltage line, an alternating current signal line and a second voltage line arranged on a substrate, wherein the substrate comprises a display region and a non-display region surrounding the display region, and the first voltage line, the alternating current signal line and the second voltage line are arranged at the non-display region;
the display substrate further comprises a first conductive layer, a first insulation layer and a second conductive layer laminated sequentially on the substrate, the first voltage line and the alternating current signal line are arranged on the first conductive layer, and the second voltage line is arranged on the second conductive layer;
the first voltage line is lapped onto the second voltage line through a first groove penetrating through the first insulation layer; and
an orthogonal projection of the second voltage line onto the substrate overlaps an orthogonal projection of the alternating current signal line onto the substrate at an overlapping region, and a ratio of an area of the overlapping region to an area of the orthogonal projection of the alternating current signal line onto the substrate is within a first predetermined ratio range;
wherein a plurality of protrusions and a plurality of recesses are arranged alternately at an edge of the second voltage line close to the display region in the overlapping region, and each protrusion protrudes towards the display region.
