A display device includes a display panel which defines first and second display areas, and includes pixels connected to data lines and scan lines, respectively, a data driving circuit which drives the data lines, a scan driving circuit which drives the scan lines, and a driving controller which receives an image signal and a control signal, control the data and scan driving circuits according to an operation mode, and output clock signals. In a multi-frequency mode, the scan driving circuit includes a first scan driving circuit corresponding to the first display area and a second scan driving circuit corresponding to the second display area. The second scan driving circuit sequentially drives first scan lines among scan lines corresponding to the second display area during a first frame, and sequentially drives second scan lines among scan lines corresponding to the second display area during a second frame.
