In the case where a conductive line can be formed, the present invention does not limit the shape of the sensing structure, the first sensing electrode, and the second sensing electrode. The capacitive touch panel disclosed in the above embodiments and the touch display panel using the same feature are described as follows: (1) Compared with the area of the grid, the conductive line is very thin. The capacitive touch panel can hardly observe the presence of conductive lines on the appearance or the giant view. (2) The material of the conductive wire and the signal transmission wire can be made of the same material, so that the conductive wire and the signal transmission wire can be formed at one time in the same process, which can save the manufacturing time of the capacitive touch panel. 9 M25338 (3). Conductive wires made of metal have a very low resistance value, so the touch signal can be transmitted quickly. (4). Conductive wires made of metal have excellent ductility, so the handleability is better, making the capacitive touch panel a flexible capacitive touch panel. (5) When the grid around the conductive line is a regular hexagon (honeycomb structure), the same amount of conductive wire can be used to obtain a larger area of the mesh, thus saving the amount of conductive wire. In summary, although the present invention has been disclosed above by way of example, it is not intended to limit the present invention. Those having ordinary knowledge in the technical field of the present invention can make various changes and refinements without departing from the spirit and scope of the present creation. Therefore, the scope of protection of this creation is subject to the definition of the patent application scope attached.
