Claim:
1. A display device, comprising: a plurality of pixels, each pixel including an organic light emitting diode and a driving transistor controlling a driving current supplied to organic light emitting diode; a plurality of data lines transmitting a plurality of data signals to the plurality of pixels; a plurality of scan lines transmitting a plurality of scan signals to the plurality of pixels; a plurality of first power lines supplying a first power source voltage to the plurality of pixels; and a plurality of power lines supplying a second power source voltage to the plurality of pixels, wherein an image is displayed while being divided into: a first field, the first field including a first compensation period in which a threshold voltage of respective driving transistors of first group pixels among the plurality of pixels is compensated, and a first light emitting period in which the first group pixels simultaneously emit light according to a programmed data signal, and a second field, the second field including a second compensation period in which a threshold voltage of respective driving transistors of second group pixels, different from the first group pixels, among the plurality of pixels is compensated, and a second light emitting period in which the second group pixels simultaneously emit light according to a programmed data signal, wherein the plurality of first power lines includes:
