Claim 10:
11. A display device comprising:
a display panel comprising a plurality of pixels 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; and
a driving controller which
divides the display panel into a first display region, a second display region and a boundary region,
controls the data driving circuit and the scan driving circuit to drive the first display region at a first driving frequency, to drive the second display region at a second driving frequency different from the first driving frequency and to drive the boundary region at a plurality of third driving frequencies during a multi-frequency mode, and
sets the plurality of third driving frequencies respectively corresponding to a plurality of horizontal lines in the boundary region during the multi-frequency mode,
wherein the boundary region is defined between the first display region and the second display region,
wherein the boundary region includes H horizontal lines including a first horizontal line to an H-th horizontal line sequentially arranged from a position adjacent to the first display region, wherein H is a natural number, and
wherein frequency levels of the plurality of third driving frequencies nonlinearly changes from the first horizontal line to the H-th horizontal line.
