Patent ID: 8537077

Claim:
A display device comprising: a light-emitting element; a first capacitor that is connected between first and second contact points; a driving transistor that has an output terminal, an input terminal that is connected to a first voltage, and a control terminal that is connected to the second contact point; a first switching transistor that is controlled by a first scanning signal and that is connected between a data voltage and the first contact point; a second switching transistor that is controlled by the first scanning signal and that is connected between a second voltage and the first contact point; a third switching transistor that is controlled by the first scanning signal and that is connected between the second contact point and the output terminal of the driving transistor; and a fourth switching transistor that is controlled by a second scanning signal and that is connected between the light-emitting element and the output terminal of the driving transistor, wherein during an entire period in which the second scanning signal maintains an intermediate voltage level in between first and second voltage levels, the first scanning signal maintains the second voltage level.
