Claim:
1. A fabrication method of a touch device, wherein the touch device has a sensing area and a peripheral area surrounding the sensing area, the method comprising: forming a sensing electrode layer extending from the sensing area to the peripheral area; forming a first shading layer having a through hole on the peripheral area to overlay the sensing electrode layer disposed on the peripheral area and to expose a part of the sensing electrode layer disposed on the peripheral area by the through hole; forming a signal transmission line layer without covering the through hole on the first shading layer; and forming a conductive layer to fill in the through hole of the first shading layer and to electrically connect the sensing electrode layer and the signal transmission line layer, wherein the conductive layer overflows a surface of the first shading layer, and wherein the overflow part of the conductive layer stretches across a surface of the signal transmission line layer for electrical connection.
