1. An organic light-emitting display device comprising:

  • a data driver configured to provide a data signal to a data line;

    a scan driver configured to provide a scan signal to a scan line; and

    a display panel comprising at least one pixel at a crossing region of the data line and the scan line, the at least one pixel comprising;

    a switching transistor comprising a gate electrode connected to the scan line and a first electrode connected to the data line;

    a first capacitor comprising a first terminal connected to a second electrode of the switching transistor and a second terminal connected to a reference voltage source;

    a second capacitor comprising a first terminal connected to the first electrode of the switching transistor via a first node and a second terminal connected to a second node;

    a driving transistor comprising a first electrode connected to a first power source via the second node, a second electrode connected to an organic light-emitting diode (OLED), and a gate electrode connected to the reference voltage source via a third node; and

    a third capacitor comprising a first terminal connected to the second node and a second terminal connected to the third node.
