Abstract:
A display apparatus includes a pixel unit in which pixels are arranged in a matrix pattern; and a driving circuit for driving the pixel unit. Each of the pixels includes a signal level holding capacitor; a first transistor that is turned on/off in response to a writing signal and via which one end of the signal level holding capacitor is connected to a signal line; a second transistor having one end of the signal level holding capacitor connected to a gate thereof and the other end of the signal level holding capacitor connected to a source thereof; a current-driven self-light-emitting element whose cathode is held at a cathode potential and whose anode is connected to the source of the second transistor; a third transistor that is turned on/off in response to a driving pulse signal; and a fourth transistor that is turned on/off in response to a control signal.
