Abstract: A display device and a method of driving the same. The display device includes a display panel including a plurality of pixels, a degradation compensator configured to output compensation data based on age values of the plurality of pixels and an input grayscale value of input image data, a scan driver configured to supply a scan signal to the display panel, and a data driver configured to supply a data signal corresponding to the compensation data to the display panel. The degradation compensator includes a first compensation unit configured to generate a first compensation grayscale value with reference to the input grayscale value and a first age value, and a second compensation unit configured to generate a second compensation grayscale value with reference to the first compensation grayscale value and the first age value.
