ABSTRACT:
A display device of active matrix driving type has a plurality of pixel regions arranged in a plane, each of the pixel regions including a selection switching element that controllably switches a supply of a signal to the each of the pixel regions, a pressure sensitive switching element that controllably switches a supply of a signal to the each of the pixel regions in response to an input of an external pressure, and a retention capacitance that retains a signal supplied to the each of the pixel regions, wherein the pressure sensitive switching element includes a semiconductor layer having a channel region, and a piezoelectric film laminated on the channel region, and the retention capacitance includes a pair of capacitance electrodes and a ferroelectric film sandwiched between the pair of capacitance electrodes.
