Abstract
The present specification provides a display device and a driving method thereof performing sampling for sensing a sampling voltage of a driving transistor using a fast mode in which a driving transistor operates by a sampling voltage formed in one storage capacitor, and data writing using the slow mode in which the driving transistor is operated by a data voltage formed in another storage capacitor.
