1. A display device comprising:
a display panel including a plurality of pixels;
a scan driver connected to the plurality of pixels through a plurality of scan lines;
a sensing circuit connected to the plurality of pixels through a plurality of sensing lines; and
a controller configured to control the scan driver and the sensing circuit,
wherein, in an active period of each frame period, the scan driver is configured to sequentially apply a sensing pulse and a scan pulse to a same scan line of the plurality of scan lines,
wherein the active period is a period in which data voltages corresponding to image data are provided to the plurality of pixels, and
wherein a pulse width of the sensing pulse is different from a pulse width of the scan pulse.
