Abstract

A touch panel includes an insulating substrate, a transparent conductive layer, a number of electrodes, a number of conductive wires, and at least one conductive zone. The transparent conductive layer corresponding to a touch area of the touch panel is fixed on the insulating substrate. The electrodes are electrically connected to the transparent conductive layer. The conductive wires are electrically connected to a controller and are respectively electrically connected to the electrodes. The at least one conductive zone has two ends. One of the two ends of the at least one conductive zone is electrically connected to the controller. The at least one conductive zone and the conductive wires are disposed in a trace area of the touch panel at a distance.
