Abstract: A touch panel for use in an ultra-high resolution display includes a transparent film substrate having one surface made of PET or the like and a transparent electrode film made of ITO film or the like that is formed on the transparent film substrate. A surface of the film substrate opposite the surface on which the transparent electrode is formed has a coating layer including a filler. The filler has an average particle size of 0.1 ?m to 0.01 ?m, and the coating layer is formed to have a surface having arithmetic particle roughness (Ra) of 0.1 ?m to 0.01 ?m, whereby the Ra of the surface of the coating layer is formed to 1/2000th to 1/4000th of the pixel pitch of a display to which the touch panel is attached.

Abstract: A touch panel of the present invention in which a piezoelectric substrate is fixed to a movable plate or a supporting substrate has a reduced weight, size, and thickness by providing simpler wiring. The touch panel comprises: a movable plate having an input manipulation surface; a supporting substrate, disposed with a slight insulation gap from the movable plate, for supporting the movable plate from a back surface thereof; conductive layers on the movable plate and the supporting substrate on their respective opposing surfaces; and a piezoelectric substrate fixed to the movable plate or the supporting substrate. A pair of driving electrodes on the piezoelectric substrate are fixed to respective opposing surfaces of the piezoelectric substrate. A conductive layer electrode of the movable plate, a conductive layer electrode of the supporting substrate, and the pair of driving electrodes of the piezoelectric substrate are withdrawn integrally using a single connector tail.
