Patent ID: 7109962

Claim:
A display device comprising: a display unit having capacitive elements arrayed at respective pixels and displaceable for turning on and off the corresponding pixels; a plurality of select lines for supplying instructions to select and unselect the pixels; a plurality of signals lines for supplying pixel signals to the pixels which have been selected; and a drive unit having drive circuits arrayed at respective pixels each for driving the corresponding capacitive element in response to an instruction from one of the select lines and a signal from one of the signal lines; each of said drive circuits having: a logic gate for inhibiting the inputting of a signal from said signal line when unselected and permitting the inputting of a signal from said signal line when selected, based on a select voltage applied from one of said select lines; a capacitor for holding the output of said 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 said capacitive element based on said control voltage.
