1. A display panel, comprising:
a display substrate; and
a touch layer disposed on at least one side of the display substrate, wherein
the display substrate comprises a display region and a bonding region located on at least one side of the display region, and the bonding region comprises a bending region and a first non-bending region, which are adjacent to each other;
the display substrate further comprises a first conductive layer at least located in the bending region;
the touch layer is located in the first non-bending region; and a first boundary of the touch layer is located in an adjacent area between the bending region and the first non-bending region;
the touch layer comprises a first electrode layer, an insulating layer and a second electrode layer, which are sequentially disposed away from the first conductive layer; and an edge of the second electrode layer overlaps an edge of the first conductive layer, and wherein
orthographic projections of first boundaries of the second electrode layer, the first electrode layer and the insulating layer on the display substrate do not overlap one another, and are sequentially located away from the bending region,
the bonding region further comprises a second non-bending region located on a side of the bending region away from the first non-bending region, and the second non-bending region is adjacent to the bending region;
the touch layer is also located in the second non-bending region; and a second boundary of the touch layer is located in an adjacent area between the bending region and the second non-bending region; and
orthographic projections of second boundaries of the second electrode layer, the first electrode layer and the insulating layer on the display substrate do not overlap one another, and are sequentially located away from the bending region.
