Abstract
A touch panel is formed by firstly forming a film layer on a first plate, and next, sequentially forming a buffer layer on the film layer, forming a sensing layer on the buffer layer, forming a second plate on the sensing layer. After the foregoing formation procedures, the first plate is removed from the film layer. Next, a cover is attached to the film layer. In this way, the film layer is located between the cover and the buffer layer. Finally, the second plate is removed from the sensing layer, so as to form a touch panel with the features of light weight, thin thickness and low costs.
