Abstract
A touch panel is provided in the present disclosure, including: a substrate, a conductive trace structure, and a light-shielding structure. The substrate includes a visible area and a peripheral area, and the visible area is surrounded by the peripheral area. A conductive trace structure is disposed on the visible area. The light-shielding structure includes a first material layer and a second material layer, in which the optical density of the light-shielding structure is lower than 4, the first material layer is disposed on the peripheral area, and the second material layer is disposed on the first material layer. A method of manufacturing a touch panel is provided in some embodiments of the present disclosure for the effects of saving cost and improving wire drift.
