摘要： A display device includes a display panel which displays an image during a plurality of driving frames, a panel driver which drives the display panel, and a driving controller which controls a driving operation of the panel driver. The driving controller divides the display panel into a first display area and a second display area based on an image signal. Each of the plurality of driving frames includes a full frame in which the first display area and the second display area are driven, and a plurality of partial frames in which only the first display area is driven. A number of the plurality of partial frames included in each of the plurality of driving frames is changed.
