1. A display panel, comprising:
a base substrate, comprising a display region, a wiring region surrounding the display region and a bonding region, and the bonding region being located at a side of the display region;
a light-emitting element arranged in the display region and comprising a cathode;
a first line and at least one second line in the wiring region, the first line being coupled to the cathode of the light-emitting element, two ends of the second line being coupled to the first line in the bonding region, and the first line and the second line being coupled through at least two via holes at an opposite side of the bonding region; and
a touch layer located on the light-emitting element, wherein the second line is arranged at a same layer and made of a same material as the touch layer, and the touch layer and the second line are forming simultaneously with a same mask through a single patterning process.
