Abstract: The display device includes a display panel and a pixel. A compensator configured to calculate a degradation rate of the pixel based on an input gray level of first image data, and compensates the first image data based on the degradation rate to generate second image data. A data driver configured to generate a data signal based on the second image data and configured to supply the data signal to the pixel. The pixel includes a first element group and a second element group connected in series to each other, the first element group includes at least one first light emitting element, and the second element group includes at least one second light emitting element. The compensator is to calculate the degradation rate by applying first information on the number of the first light emitting elements and second information on the number of the second light emitting elements.
