The sensing layer electrically connected to the control circuit layer includes plural sensing cell, and the dielectric layer is flexible. The touch operation layer is flexible as well and includes a button area and an adjacent non-button area. The button area includes a ground plane stacked on the dielectric layer and a first touch cover stacked on the ground plane, and the non-button area includes a second touch cover stacked on the dielectric layer. Plural though openings are provided in the button area corresponding to the sensing cells such that a portion of the dielectric layer is exposed.
