1. A display device comprising:
a display panel comprising a first display area and a second display area, each of the first display area and the second display area including a plurality of pixels, and a pixel of the plurality of pixels being connected to a corresponding data line of a plurality of data lines and corresponding scan lines of a plurality of scan lines;
a data driving circuit which drives the plurality of data lines;
a scan driving circuit which drives the 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,
wherein 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.
