A display device may include a display panel including a plurality of pixels and sensing lines respectively coupled to the pixels, a degradation compensator configured to detect a degradation of the pixels based on a current flowing through the pixels and to compensate a brightness and a color difference of a first region including at least one of the pixels coupled to a respective one of the sensing lines, through which the degradation is detected, based on a first sensing data of the first region and a second sensing data of a second region including pixels adjacent the pixels of the first region, a data driver configured to provide data signals to data lines, a scan driver configured to provide scan signals to the pixels, and a timing controller configured to generate control signals which control the degradation compensator, the data driver, and the scan driver.
