Abstract: A display device includes a display panel including a pixel, a driving controller that receives an image signal and outputs an image data signal in which the image signal is compensated, and a data driving circuit that provides the pixel with a data signal corresponding to the image data signal. The driving controller includes a memory, a hysteresis calculator that calculates a current hysteresis state value of a current frame based on the image signal and a previous hysteresis state value of a previous frame, which is stored in the memory, and stores the current hysteresis state value in the memory, and a compensator that calculates a compensation value based on the image signal and the previous hysteresis state value stored in the memory and compensates for the image signal depending on the compensation value to output the image data signal.
