Abstract
A display device comprises: a display panel including a light emitting element, a driving transistor providing a driving current to the light emitting element using a high potential driving voltage and switching transistors controlling the driving transistor; a gate driving circuit supplying scan signals to the display panel; a data driving circuit generating a data voltage or a bias voltage using a feedback high potential driving voltage transmitted through a high potential driving voltage feedback line; and a timing controller controlling the gate driving circuit and the data driving circuit so that the data voltage is supplied to the display panel in a first period at a low speed mode which the display panel is driven at predetermined driving frequency less than a frequency of a high speed mode and the bias voltage is supplied to the display panel in a second period at a low speed mode.
