A touch display panel includes a substrate, a first metal layer, a second metal layer, common electrode pads, and a driving IC. The substrate includes a display area and a non-display area. The first metal layer disposed on the substrate includes gate lines and first metal wires, wherein the gate lines extend along a first direction. The second metal layer disposed on the substrate includes data lines and second metal wires, wherein the data lines extend along a second direction. The common electrode pads are disposed on the display area along the first direction and the second direction. The first metal wires and/or second metal wires are connected the common electrode pads and the driving IC. The first metal wires and/or second metal wires extend to the non-display area and extend to the display area along the first direction.
