1. 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.
