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.
