Abstract: A display device includes: a display panel including a plurality of pixels; a deterioration compensator that outputs compensation data based on a lifetime value of the plurality of pixels and an input grayscale of input image data; a scan driver that supplies a scan signal to the display panel; and a data driver that supplies a data signal corresponding to the compensation data to the display panel. The deterioration compensator includes a grayscale-current converter that calculates an input current corresponding to the input grayscale.
