A display device comprises a display panel including a plurality of compensation areas, each of which includes at least one pixel, a driving controller including a compensation controller and a luminance color compensator, performing a luminance and color compensation for each of the compensation areas, and generating a voltage code and a data signal, a gamma reference voltage generator receiving the voltage code and generating a gamma reference voltage based on the voltage code, and a data driver connected to the driving controller and the gamma reference voltage generator and generating a data voltage based on the data signal and the gamma reference voltage. Each of the compensation areas after the luminance and color compensation may have a target gamma value and a target color coordinate. The compensation areas may be shifted while the luminance color compensation is performed.
