Abstract: The present invention provides a display device and a method of driving the same. The display device includes: a light-emitting device; a first capacitor connected between a first contact point and a second contact point; a driving transistor including an input terminal connected to a first voltage, an output terminal, and a control terminal connected to the second contact point; a first switching transistor controlled by a first control signal and connected between a data voltage and the first contact point; a second switching transistor controlled by a second control signal and connected between a second voltage and the first contact point; a third switching transistor controlled by a third control signal and connected between the second contact point and the second voltage; a fourth switching transistor controlled by the first control signal and connected between the second contact point and the output terminal of the driving transistor; and a fifth switching transistor controlled by the second control signal and connected between the light-emitting device and the output terminal of the driving transistor.
