1. A display device comprising a plurality of pixels, each pixel including:

  • a light emitting element;

    a capacitor;

    a driving transistor having a control terminal, an input terminal, and an output terminal and supplying a driving current to the light emitting element to emit light;

    a first switching unit diode-connecting the driving transistor and supplying a data voltage to the capacitor in response to a scanning signal; and

    a second switching unit supplying a driving voltage to the driving transistor and connecting the capacitor to the driving transistor in response to an emission signal, wherein the capacitor is connected to the driving transistor through the first switching unit, stores a control voltage depending on the data voltage and a threshold voltage of the driving transistor, and is connected to the driving transistor through the second switching unit to supply the control voltage to the driving transistor.
