    Abstract: A display device which includes a display panel that includes a first display area and a second display area, and a driving controller. During a multi-frequency mode, the driving controller drives the first display area by using a first driving frequency and drives the second display area by using a second driving frequency. During the multi-frequency mode, when the second driving frequency changes from a first frequency to a second frequency, the driving controller drives the first display area and the second display area during at least one frame by using a base frequency, drives the first display area and the second display area during at least one second frame by using an intermediate frequency between the base frequency and the second frequency, and then drives the first display area by using the first driving frequency and drives the second display area by using the second frequency.

    Abstract: A display device includes a display panel including a first pixel connected to a first initialization scan line and a first compensation scan line and a second pixel connected to a second initialization scan line and a second compensation scan line, a scan driving circuit which provides a first initialization scan signal to the first initialization scan line and the second initialization scan line in common and provides a first compensation scan signal and a second compensation scan signal to the first compensation scan line and the second compensation scan line, and a driving controller which controls the scan driving circuit. A delay time from a time point at which the first initialization scan signal transitions from an active level to an inactive level to a time point at which the first compensation scan signal transitions from the inactive level to the active level is less than one horizontal period.

    Abstract: A display substrate including a scan driving circuit, a scan line, and an insulating pattern. The scan driving circuit includes a connection electrode disposed on a plurality of insulating layers, a plurality of signal lines, and a stage circuit connected to the signal lines and overlaps a non-display area. The scan line overlaps a display area and is connected to the scan driving circuit. The insulating pattern is disposed on the insulating layers, covers the connection electrode, and makes contact with a sealant.
