Abstract
A touch panel is provided. The touch panel includes a cover plate and a display element under the cover plate. A touch sensing layer is disposed at an active area of the touch panel and between the cover plate and the display element. A decorative layer is disposed at a peripheral area of the touch panel and between the cover plate and the display element, wherein the active area is surrounded by the peripheral area. The touch panel further includes a dielectric layer disposed between the cover plate and the display element, wherein the difference in reflectivity between the active area and the peripheral area is 0 to 0.5.
