1. A display panel, comprising a display substrate and a touch panel arranged on the display substrate, wherein
the display substrate comprises multiple sub-pixels, and at least one of the sub-pixels comprises an emitting region and a non-emitting region located on a periphery of the emitting region;
the touch panel comprises multiple touch electrodes, and at least one of the touch electrodes comprises multiple grid patterns enclosed by metal wires;
an orthographic projection of the emitting region on the display substrate is located within a range of an orthographic projection of a region enclosed by the metal wires on the display substrate;
an orthographic projection of the metal wires on the display substrate is located within a range of an orthographic projection of the non-emitting region on the display substrate;
the touch panel comprises a touch region, a bonding region located at a side of the touch region, and a border region located at another side of the touch region;
a signal lead, a grounding wire and an auxiliary grounding wire are arranged in the border region;
a first end of the signal lead is connected with a touch electrode in the touch region, and a second end of the signal lead extends to the bonding region along a border shape;
a first end of the grounding wire is arranged at a side of the border region away from the bonding region, and a second end of the grounding wire extends to the bonding region along the border shape at a side of the signal lead away from the touch region; and
a first end of the auxiliary grounding wire is arranged at the side of the border region away from the bonding region, and a second end of the auxiliary grounding wire is connected with the grounding wire after extending along the border shape.
