Patent ID: 8872738

Claim:
A display device comprising: an insulating layer; a display unit provided on a major surface of the insulating layer and including: a plurality of gate lines; a plurality of signal lines; a plurality of power source lines; and a plurality of pixel units arranged in a matrix configuration; and an organic EL layer provided on the display unit, each of the pixel units including: a drive transistor including a drive gate electrode, a drive source electrode, and a drive drain electrode, the drive drain electrode being connected to one of the power source lines, a current to flow between the drive source electrode and the drive drain electrode being configured to increase as increasing a voltage of the drive gate electrode with respect to the drive source electrode, a write transistor including a write gate electrode, a write source electrode, and a write drain electrode, the write gate electrode being connected to one of the gate line, the write source electrode being connected to one of the signal line, the write drain electrode being connected to the drive gate electrode, and a resistor including a diode having an anode and a cathode, the anode being connected to the drive gate electrode, the cathode being connected to the power source line, and a resistance in an inverse direction of the diode being lower than a resistance of the write transistor in an OFF-state and being more than 100 times a resistance of the write transistor in an ON-state.
