摘要:
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.
