1. A display device comprising:

  • a plurality of pixels including;

    a first capacitor connected between a data line and a first node;

    a switching transistor connecting the first node and a second node;

    a first light emitting transistor transmitting a first power source voltage to the second node;

    a driving transistor having one electrode connected to the second node and controlling a driving current flowing to an organic light emitting diode (OLED); and

    a reference voltage transistor transmitting a reference voltage to the first node, wherein, when the first power source voltage is applied to the second node through the first light emitting transistor such that a light emitting step in which the organic light emitting diode (OLED) emits light is simultaneously performed in a plurality of pixels, the switching transistor is turned off and the reference voltage transistor is turned on such that the reference voltage is transmitted to the first node, and a data voltage corresponding to a scan signal of a gate-on voltage respectively corresponding to a plurality of pixels is stored to the first capacitor.
