Abstract
A touch panel includes a substrate, a touch sensing electrode, a peripheral conductive trace, a protective layer, and a conductive layer. The substrate has a display area and a peripheral area. The touch sensing electrode is disposed in the display area. The peripheral conductive trace is disposed in the peripheral area. The touch sensing electrode is electrically connected to the peripheral conductive trace. The touch sensing electrode and the peripheral conductive trace at least include metal nanowires. The protective layer is disposed on the touch sensing electrode, and the conductive layer is disposed on the peripheral conductive trace.
