Abstract:
A display device includes: a first pixel region including first pixels, each of the first pixels including a driving transistor to be initialized by a first initialization power source supplied from a first power line; a second pixel region including second pixels, each of the second pixels including a driving transistor to be initialized by a second initialization power source supplied from a second power line; and a power supplier to supply the first initialization power source and the second initialization power source, the first initialization power source and the second initialization power source having a same voltage level when the display device is driven in a first mode, and the first initialization power source and the second initialization power source having different voltage levels during at least one frame period when the display device is driven in a second mode.
