Furthermore, some of the wires are not covered by the protective layer, so that the wires not covered by the protective layer are easily contacted with air to cause oxidation, thereby causing a decrease in the wire properties of the wires.

The main purpose of the present invention is to provide a touch panel and a touch display panel to solve the problem of open circuit caused by the alignment error of the external circuit device and the ground pad due to the protective layer.

To achieve the above, the present invention provides a touch panel including a transparent substrate, a touch sensing component, a plurality of connection pads, a first ground pad, a plurality of wires, and at least two ground wires. The touch sensing component is disposed on the transparent substrate. The connection pad is disposed on the transparent substrate. The first ground pad is disposed on the transparent substrate and disposed between the connection pads. The wires are disposed on the transparent substrate, and the wires are electrically connected to the connection pads and the touch sensing components. The grounding wire is disposed on the transparent substrate and electrically connected to the grounding pad.

To achieve the above objective, the present invention provides a touch display panel including a touch panel and a display panel. The touch panel includes a transparent substrate, a touch sensing component, a plurality of connection pads, a first ground pad, a plurality of wires, and at least two ground wires. The touch sensing component is disposed on the transparent substrate. The connection pad is disposed on the transparent substrate. The first ground pad is disposed on the transparent substrate and disposed between the connection pads.
