1. A touch display panel, comprising:
a first conductive layer comprising a plurality of touch electrodes arranged along a first direction and a second direction, the first direction being different from the second direction, and the plurality of touch electrodes comprising a first touch electrode;
a second conductive layer arranged on one side of the first conductive layer; and
an insulation layer arranged between the first conductive layer and the second conductive layer;
wherein the second conductive layer comprises a first touch lead and a first auxiliary structure both overlapped with the first touch electrode, and the first auxiliary structure is located on at least one side of the first touch lead;
the first conductive layer further comprises a second touch electrode arranged along the first direction with the first touch electrode, and the first touch lead extends to overlap with and electrically connect to the second touch electrode;
the second conductive layer further comprises a second auxiliary structure overlapped with the second touch electrode, and the second auxiliary structure is located on at least one side of the first touch lead;
the second conductive layer further comprises a second touch lead overlapped with and electrically connected to the first touch electrode, and the second touch lead extends to overlap with the second touch electrode; and
an overlapping area of the second auxiliary structure and the second touch electrode is equal to an overlapping area of the first touch electrode and the first auxiliary structure.
