Problems solved by technology

[0010] Specifically, the known technology must add steps for making the insulating layer 312, but this will increase the man-hours and costs of manufacturing the transparent capacitive touch panel 300. In addition, the insulating layer 312 must have a contact window (contact window) (not shown). ) to electrically conduct the upper indium tin oxide layer 316 to the integrated circuit (IC) (not shown) on the transparent substrate 310, so that it is necessary to add a photomask process to make the contact window, and greatly improve the transparent capacitive Manufacturing Cost and Difficulty of the Touch Panel 300

[0059] The aforementioned embodiments all have a single-layer structure, wherein the first transparent electrode layer and the second transparent electrode layer are respectively disposed on the surfaces of the transparent substrate and the transparent cover plate. In the present invention, both the first transparent electrode layer and the second transparent electrode layer can be fabricated on the surface of the transparent cover plate, so that the thickness of the transparent capacitive touch panel can be greatly reduced without using a transparent substrate. Hereinafter, another embodiment will be given and described with illustrations. However, in order to avoid confusion with the above-mentioned embodiments, each component will be indicated by other symbols.
