Touch panel and manufacturing method thereof

A touch panel, comprising:

• a substrate having a display area and a peripheral area;
• a photosensitive layer and a metal nanowire layer comprising a plurality of metal nanowires disposed on the substrate,
• wherein the photosensitive layer is made of a photoresist material comprising a polymer or a mixture of polymer, and
• wherein the disposal of the photosensitive layer and the metal nanowire layer on the substrate comprising:
• allowing the photoresist material to permeate or penetrate into spaces between the metal nanowires of the metal nanowire layer, and
• curing the photoresist material of the photosensitive layer to form a composite layer of the photosensitive layer and the metal nanowire layer, such that the metal nanowires of the metal nanowire layer are embedded in the photosensitive layer;
• and
• a photosensitive conductive layer disposed on the peripheral area,
• wherein a first removal region is defined on the display area and a second removal region is defined on the peripheral area after an exposure,
• wherein, in the display area, the photosensitive layer and the metal nanowire layer in the first removal region are removed by a developer, such that a touch sensing electrode is formed in the display area, and in the peripheral area, the photosensitive conductive layer, the photosensitive layer, and the metal nanowire layer in the second removal region are removed by the developer, such that a peripheral conductive trace is formed in the peripheral area, and
• wherein the touch sensing electrode is electrically connected to the peripheral conductive trace.
