A pixel, a display device including a plurality of pixels, and a method of driving the display device. The display device includes: an emission pixel comprising an emission device, the emission pixel being in a display area; a dummy pixel in a non-display area outside the display area; and a repair line that is connectable to the emission device of the emission pixel and the dummy pixel, wherein the dummy pixel includes: a first dummy driver for receiving a same data signal as the data signal applied to the emission pixel for each of a plurality of subfields of one frame and controlling emission of the emission device of the emission pixel via the repair line; and a second dummy driver for resetting the repair line in one of the subfields in which the emission device does not emit light.
