1. A driving method of a display device, the method comprising:
dividing a display panel into a first display region and a second display region in a way such that the first display region is driven at a first driving frequency and the second display region is driven at a second driving frequency;
outputting a start signal and a masking signal, the masking signal indicating a start of the second display region;
sequentially driving a plurality of scan lines in synchronization with the start signal, and
stopping the driving of scan lines, corresponding to the second display region, of the plurality of scan lines in response to the masking signal,
wherein an active level of the start signal indicates a start of each of a plurality of frames,
wherein the number of the active level of the start signal during a predetermined time in a first mode is greater than the number of the active level of the start signal during the predetermined time in a second mode, and
wherein a first frame among the plurality of frames has a first duration, and a second frame among the plurality of frames has a second duration different from the first duration, during the first mode.
