Abstract
A touch panel including a substrate, a touch-sensing element, transmission lines, a ground electrode, a first electrode layer, an insulation layer and a second electrode layer is provided. The transmission lines are electrically connected to the touch-sensing element. The ground electrode surrounds the touch-sensing element and the transmission lines. The first electrode layer is located around and electrically connected to the ground electrode. The insulation layer is at least disposed on the first electrode layer. The second electrode layer is disposed on the insulation layer to form at least one capacitance storage unit, so that the electro static discharge can be conducted to the ground electrode through the capacitance storage unit.
