Abstract
Disclosed is an organic light emitting display device. In a sensing mode of sensing a threshold voltage of a driving transistor, when ripple occurs in a driving voltage applied to a drain of the driving transistor, an error may occur in the sensed threshold voltage. Therefore, when sensing a threshold voltage of a driving transistor, the display device corrects a threshold voltage of a driving transistor of each pixel included in a horizontal line having an error caused by a ripple of a driving voltage, to a threshold voltage of each pixel included in another horizontal line.
