Abstract
A touch panel includes a substrate, a touch electrode, a control unit, and a trace structure. The substrate has a touch sensing area and a peripheral circuit area. The touch electrode is disposed on the touch sensing area of the substrate. The touch electrode includes a first transparent conductive layer, a second transparent conductive layer, and a metal mesh layer. The second transparent conductive layer is disposed on the first transparent conductive layer. The metal mesh layer is disposed between the first transparent conductive layer and the second transparent conductive layer, in which the metal mesh layer is at least partially in contact with the first transparent conductive layer and the second transparent conductive layer, and the metal mesh layer comprises plural metal lines. The trace structure is disposed on the peripheral circuit area of the substrate and configured to electrically connect the touch electrode to the control unit.
