<p>Disclosed is an organic EL display device which comprises: a light emitting pixel (170) that comprises a drive transistor (173), a scan transistor (171), a reset transistor (172), a capacitor (174) that is inserted between the gate electrode and the source electrode of the drive transistor (173), and a light emitting element (175) that is connected to the source electrode of the drive transistor (173); and a drive circuit. The drive transistor (173) comprises a back gate electrode. The drive circuit electrically disconnects the drive transistor (173) by applying a predetermined bias voltage to the back gate electrode and making the threshold voltage of the drive transistor (173) larger than the potential difference between the gate electrode and the source electrode, and has the capacitor (174) hold a voltage that corresponds to a signal voltage, while maintaining the drive transistor (173) in the electrically disconnected state.</p> |
