Abstract
A display device includes a display panel including pixels connected to data lines and scan lines, a data driving circuit which drives the data lines, a scan driving circuit which drives the scan lines, and a driving controller divides the display panel into first and second display regions, controls the data driving circuit and the scan driving circuit to drive the first display region at a first driving frequency and to drive the second display region at a second driving frequency lower than the first driving frequency, and sets third driving frequencies respectively corresponding to horizontal lines in a boundary region, which is defined by a portion of the second display region adjacent to the first display region, during a multi-frequency mode. Each of the third driving frequencies has a frequency level between the first driving frequency and the second driving frequency.
