1. A manufacturing method of touch panel, comprising steps of:
providing a substrate and defining a touch section and a non-touch section; disposing a shield layer on the non-touch section of the substrate; disposing a touch electrode layer with multiple touch electrodes on the touch section and the non-touch section of the substrate; covering the touch electrode layer with a metal mask and forming a metal wiring layer with multiple metal wires on a section of the non-touch section, which section is not covered by the metal mask and then removing the metal mask; performing lithography and etching processes to the touch electrode layer so as to form multiple touch electrodes; disposing an insulation layer on the junctions between the touch electrodes and the metal wires, the insulation layer being preformed with multiple electrical connection holes; disposing a lead layer with multiple metal leads on the insulation layer, the metal leads passing through the electrical connection holes to electrically connect with the metal wires and the touch electrodes; and disposing a protection layer on the touch electrode layer and the metal wiring layer and the insulation layer.
