Abstract
A display device includes a display panel including pixels, a data driver receiving sensing data corresponding to a driving current value of a driving transistor of each of the pixels, and a driving controller calculating a change amount of the sensing data, determining bad pixels based on the change amount of the sensing data, and performing a panel protection operation based on a number of the bad pixels.
