Abstract
A three-dimensional curved touch panel includes a light-transmissivity substrate and a touch-sensing module. The light-transmissivity substrate has a three-dimensional curved surface. The three-dimensional curved surface is defined with a sensing area and a surrounding area surrounding the sensing area. The touch-sensing module is bonded to the sensing area and the surrounding area of the three-dimensional curved surface. The touch-sensing module is provided with two indentations which are opposite to each other at an edge thereof. The indentations are located in the surrounding area, and the sensing area is located between the indentations.
