Abstract: A display device includes a display panel including a pixel connected to scan lines and a data line, a scan driving circuit, a data driving circuit, and a driving controller that controls the scan driving circuit and the data driving circuit. The pixel includes a light-emitting diode and an initialization transistor connected between a first initialization voltage line and a first electrode of the light-emitting diode and including a gate electrode connected to a first scan line among the scan lines. A first scan signal provided to the first scan line during a blank period has an active level during a predetermined initialization time duration, and the predetermined initialization time duration is set to a time duration corresponding to a luminance characteristic of the display panel.
