Abstract: A touch panel, which contains a substrate, a mask layer, a sensing circuit layer and a barrier layer, is disclosed. The mask layer is disposed around the bottom surface of the substrate. The sensing circuit layer is located on the same side of the substrate with the mask layer, and the surrounding area of the sensing circuit layer is shielded by the mask layer. In addition, the area of the sensing circuit layer exposed from the mask layer is defined as a sensing region. Furthermore, the barrier layer is disposed between the substrate and the sensing circuit layer and between the mask layer and the sensing circuit layer. Concurrently, the barrier layer further provides separation between the mask layer and the sensing circuit layer. The barrier layer has a transparent appearance. Particularly, the barrier layer is provided for changing optical refraction and harmonizing optical reflection index and transmittance.
