1. A pixel comprising:

  • an organic light emitting diode;

    a storage capacitor coupled between a first power supply and an initialization power supply and being charged with a voltage corresponding to a data signal;

    a first transistor controlling an amount of an electric current supplied to the organic light emitting diode corresponding to the voltage charged in the storage capacitor;

    a second transistor coupled between a data line and a current scan line, supplying the data signal to a first electrode of the first transistor when a scan signal is supplied to the current scan line;

    a third transistor coupled between a gate electrode and a second electrode of the first transistor, and being turned-on when the scan signal is supplied to the current scan line; and

    a boosting capacitor coupled between the current scan line and the gate electrode of the first transistor, boosting a voltage of the gate electrode of the first transistor when a supply of the scan signal to the current scan line stops.
