Abstract

A touch panel includes a substrate, a photosensitive layer, a metal nanowire layer and a photosensitive conductive layer. The metal nanowire layer and the photosensitive layer are formed on a display area and a peripheral area of the substrate. The photosensitive conductive layer is formed on the metal nanowire layer on the peripheral area. A removal region and a reserved region of both the photosensitive conductive layer and the photosensitive layer are defined by an exposure process. At the display area, the photosensitive layer and the metal nanowire layer in the removal region are removed by a developer to form a touch sensing electrode. At the peripheral area, the photosensitive conductive layer, the photosensitive layer and the metal nanowire layer in the removal region are removed by a developer to form a peripheral conductive trace. The touch sensing electrode is electrically connected to the peripheral conductive trace.
