Claim 10:
11. A display device comprising:
a display panel including a plurality of pixels;
a driving controller, which receives an input image signal and a control signal, and to output a voltage control signal;
a voltage generator, which generates a first voltage and a second voltage in response to the voltage control signal; and
a scan driving circuit, which receives the first voltage and the second voltage and provides a plurality of scan signals to the plurality of pixels,
wherein the display panel is divided into a first display region driven at a first operating frequency and a second display region driven at a second operating frequency,
wherein the driving controller outputs the voltage control signal, to generate the first voltage in a first high voltage level and the second voltage in a first low voltage level, when the first display region is driven,
wherein the driving controller outputs the voltage control signal, to generate the first voltage in the first high voltage level and the second voltage in the first low voltage level, when a first horizontal line to an A-th horizontal line of pixels of the plurality of pixels in the second display region are driven,
wherein the driving controller outputs the voltage control signal, to generate the first voltage in a second high voltage level and the second voltage in a second low voltage level, when an (A+1)-th horizontal line to an n-th horizontal line in the second display region are driven, and
wherein ‘A’ is a positive integer and changes at every frame, ‘n’ is a positive integer, and A<n.
