Abstract
Disclosed are an organic light emitting display device and a display panel thereof, which are capable of performing a recovery driving for recovering a threshold voltage of a driving transistor to be within a range of compensation for the threshold voltage if the threshold voltage of the driving transistor deviates from the range of the compensation for the threshold voltage as a driving time of the driving transistor of a pixel increases.
