Abstract: A display device includes a display panel that includes a first display area and a second display area, a data driving circuit which drives a plurality of data lines, a scan driving circuit which drives a plurality of scan lines, and a driving controller which controls the data driving circuit and the scan driving circuit such that the first display area is driven at a first driving frequency, and the second display area is driven at a second driving frequency lower than the first driving frequency during a multi-frequency mode, where the driving controller receives an image signal and provides to the data driving circuit an image data signal obtained by compensating for a gamma level of the image signal corresponding to the second display area during the multi-frequency mode.
