1. A display substrate, comprising a display region and a peripheral region surrounding the display region, wherein the peripheral region comprises a first edge extending in a first direction, a second edge extending in a second direction and a transition edge between the first edge and the second edge, and the first direction and the second direction intersect; and
wherein the display substrate comprises a base substrate and an encapsulation layer located on the base substrate, the display substrate further comprises a plurality of through holes, the through holes are located between the base substrate and the encapsulation layer, the through holes comprise a first through hole located at the transition edge, the first through hole comprises first target through holes, a cross section of each of the first target through holes in a direction parallel to the base substrate is of a long strip shape, and length directions of the first target through holes intersect with the first direction and the second direction;
wherein each of the first target through holes comprises a first boundary and a second boundary, a length of the first boundary is greater than a length of the second boundary, and an extension direction of the first boundary intersects with the first direction and the second direction;
wherein the length directions of at least some of the first target through holes intersect with each other;
wherein an angle between the length direction of the first target through holes and the second direction gradually increases from 0 degree to 90 degrees in a direction from the first edge to the second edge, and the first target through holes extend radially from a certain location near the display region as a center point to various locations of the transition edge in a diffuse way.
