1. A display device comprising:
a plurality of scan lines;
a data line;
a display panel including a pixel connected to the plurality of scan lines and the data line, the pixel including:
a light-emitting diode including a first electrode and a second electrode; and
an initialization transistor connected between a first initialization voltage line and the first electrode of the light-emitting diode and including a gate electrode connected to a first scan line among the plurality of scan lines;
a scan driving circuit which outputs a plurality of scan signals to the plurality of scan lines, respectively;
a data driving circuit which outputs a data signal to the data line during an active period; and
a driving controller which controls the scan driving circuit and the data driving circuit,
wherein a first scan signal among the plurality of scan signals 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 so that the predetermined initialization time duration has different values corresponding to different values of the luminance characteristic of the display panel.
