1. A display panel, having a display area and a non-display area on at least one side of the display area;
the display panel comprising:
a first substrate;
a first metal layer on the first substrate, wherein the first metal layer comprises a first metal part disposed in the display area and a second metal part disposed in the non-display area; and
a second metal layer on a side of the first metal layer away from the first substrate, wherein the second metal layer comprises a third metal part in the display area and a fourth metal part in the non-display area;
wherein the first metal layer and the second metal layer are separated by an insulating layer; an orthogonal projection of the first metal part on the first substrate does not overlap with an orthogonal projection of the third metal part on the first substrate, an orthogonal projection of the second metal part on the first substrate overlaps with an orthogonal projection of the fourth metal part on the first substrate, and the second metal part and the fourth metal part are electrically connected;
wherein the display panel further comprises:
a plurality of thin-film transistors in the display area, wherein each of the thin-film transistors comprises a gate and an active part;
a plurality of pixel electrodes, wherein each of the pixel electrodes is spaced from an end of the active part of at least one of the thin-film transistors;
a common electrode, wherein the common electrode is disposed on a side of at least one of the pixel electrodes away from the first substrate, and comprises a first common part in the display area and a second common part in the non-display area;
wherein the gate of each of the thin-film transistors is the first metal part, and each of the pixel electrodes is the third metal part, the second metal part is electrically connected to the second common part through a first via hole, and the fourth metal part is electrically connected to the second common part through a second via hole.
