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.

The three-dimensional printing apparatus includes a tank, a platform, a lighting module, a control unit, a photosensitizer coating unit, and an exposure and development unit. The tank is filled with a liquid forming material, and the platform is movably disposed above the tank. The lighting module is used for providing light projecting toward the liquid forming material. The control unit coupled to the platform and the lighting module is configured to control the platform to move along a first direction, such that at least one layer object of a three-dimensional object is cured on the platform by layer. The photosensitizer coating unit is coupled to the control unit and configured to form at least one photosensitizer film on the layer object. The exposure and development unit is coupled to the control unit and configured to expose the photosensitizer film by exposing and developing to color the three-dimensional object.
