Claim 0:
1. A display device comprising:
a display panel comprising a plurality of pixels respectively connected to a plurality of data lines and 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 in response to a start signal and a masking signal; and
a driving controller which receives an image signal and a control signal and output the start signal for indicating a start of one frame and the masking signal,
wherein the driving controller divides the display panel into a first display area and a second display area during a multi-frequency mode,
wherein the start signal comprises a first frame having a first duration and a second frame consecutive to the first frame having a second duration during the multi-frequency mode, the second duration is shorter than the first duration, and the masking signal indicates a start of the second display area, and
wherein the start signal comprises a third frame having a third duration during a single-frequency mode, the first duration is longer than the third duration,
wherein the driving controller provides image data signals corresponding to the first display area and the second display area to the data driving circuit during the first frame of the multi-frequency mode, and provides an image data signal corresponding to the first display area to the data driving circuit during the second frame of the multi-frequency mode.
