1. A touch panel comprising:
a planar region and a bent region located on at least one side of the planar region;
wherein the touch panel has at least one notch adjacent to the bent region; the touch panel comprises at least one first touch peripheral region located around the at least one notch, and a light-transmitting first trace layer is provided in the at least one first touch peripheral region;
further comprising at least one second touch peripheral region that is at least partially overlapped with at least one bent region, a second trace layer is provided in the at least one second touch peripheral region, and the second trace layer and the first trace layer are of a different-layer structure; and
the first trace layer in the first touch peripheral region is electrically connected with a second trace layer in an adjacent second touch peripheral region.
