Abstract
A display device includes a display unit including a plurality of pixels and a sensing unit disposed outside the display unit, where the sensing unit senses deterioration information of a driving transistor in each of the pixels through a plurality of sensing lines, and compensates for deterioration of the driving transistor. the sensing unit senses the deterioration information during a first sensing period, and the first sensing period is included in each of a power-off period in which power for the display device to display an image is not supplied, a power-on period in which the display device is turned on, and an image display period in which the image is continuously displayed after the display device is turned on.
