A display device has drive circuits each having a logic gate for
inhibiting the inputting of a data signal from a signal line when
unselected and permitting the inputting of a data signal from the signal
line when selected, based on a drive signal (select voltage) applied from
a select line, a capacitor for holding the output of the logic gate when
selected and outputting the held output as a control voltage, and a drive
voltage generating circuit for generating a drive voltage for displacing
the actuator based on the control voltage from the capacitor.
