Abstract

A display device and a method of driving the same, in which the display device includes: a light-emitting element; a first capacitor connected between first and second contact points; a driving transistor that has a control terminal connected to the second contact point, an input terminal connected to a driving voltage, and an output terminal connected to the light-emitting element; a first switching transistor connected between a data voltage or a sustain voltage and the first contact point; a second switching transistor connected between the second contact point and the output terminal of the driving transistor; and a third switching transistor connected between a reference current source and the output terminal of the driving transistor.
