A display device includes a display panel including pixels, a data driver configured to provide a data signal and an emission voltage to the pixels through the data lines, a scan driver configured to provide a scan signal to the pixels through the scan lines, a power voltage provider configured to provide a high power voltage to the pixels through a high power voltage line and to provide a low power voltage to the pixels through a low power voltage line, and a timing controller configured to generate control signals that control the data driver and the scan driver. The display panel includes a power controller that determines whether the data line is coupled to the high power voltage line or to the low power voltage line.
