1. A display panel having a display area and a non-display area around the display area, comprising:
a first metal layer having at least one first wire, wherein the first wire extends from the display area to the non-display area;
a first insulating layer disposed in the display area and the non-display area and covering the first metal layer, wherein the first insulating layer has at least one first through hole passing through the first insulating layer and extending to a surface of one of the at least one first wire;
a second metal layer having at least one second wire, wherein each of the at least one second wire is disposed on the first insulating layer in the non-display area and correspondingly connects one of the at least one first wire through one of the at least one first through hole;
a second insulating layer disposed in the display area and the non-display area and covering the first insulating layer and the first metal layer, wherein the second insulating layer has at least one second through hole passing through the second insulating layer and extending to a surface of one of the at least one second wire;
a third metal layer having at least one third wire, wherein each of the at least one third wire is disposed on the second insulating layer in the non-display area; and
a bridging layer having at least one bridging wire, wherein each of the at least one bridging wire extends from one of the at least one second wire in one of the at least one second through hole to one of the at least one the third wire corresponding to the one of the at least one the second wire,
wherein the first insulating layer further has at least one fifth through hole passing through the first insulating layer and extending to a surface of one of the at least one first wire; and
the second metal layer further has at least one fourth wire, each of the at least one fourth wire is disposed on the first insulating layer in the display area, each of the at least one fourth wire correspondingly passes through one of the at least one fifth through hole and connects one of the at least one first wire corresponding to the one of the at least one fifth through hole.
