Abstract
A display device includes plural scan lines, plural data lines intersecting the of scan lines, plural discharge lines for the respective scan lines; and plural pixel circuits for respective intersections of the scan lines and the data lines. Each of the pixel circuits includes a driving transistor, a first diode in which the cathode is connected to a power supply voltage line and the anode is connected to the source of the driving transistor, a retention capacitor connected between the gate and the source of the driving transistor, a selection transistor in which one of the drain and the source being connected to a data line and the other being connected to the gate of the driving transistor, and a second diode in which the cathode is connected to a discharge line and the anode is connected to the source of the driving transistor.
