Patent ID: 8552938

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 a 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 a second scanning signal and that is connected between the second contact point and the output terminal of the driving transistor; a fourth switching transistor that is controlled by a third scanning signal and that is connected between the light-emitting element and the output terminal of the driving transistor; and a fifth switching transistor that is controlled by a fourth scanning signal and that is connected between the second voltage and the second contact point, wherein the first, second, third, and fourth scanning signals consist of a high voltage and a low voltage, and periods in which each of the second and fourth scanning signals is a high voltage do not overlap.
