Abstract
A display device includes a casing () an operation plate, a piezoelectric sensor, a controller, and a display. The piezoelectric sensor includes a piezoelectric film, an optically clear adhesive, a plurality of first electrodes, a plurality of first wiring lines, a plurality of second electrodes, a second wiring line, a pair of substrates and a reception circuit. The piezoelectric sensor is bonded to a surface of the operation plate on a side opposite to an operation surface. The plurality of first wiring lines includes a region, which overlaps one of the piezoelectric film and the plurality of second electrodes but does not overlap either the piezoelectric film or the plurality of second electrodes at the same time when a first surface is viewed from a front. The region is provided between the second electrodes when the first surface is viewed from the front.
