Abstract: A display device includes a driving controller controlling a data driving circuit and providing a clock signal and a driving voltage in response to an image signal and a control signal received from an external source. The driving controller restores a data enable signal having a display period and a blank period in one frame on the basis of the control signal and sets a voltage level of the driving voltage applied to the gate driving circuit in accordance with a duration of the blank period. During a sequence of frames having a changing frame rate, the driving voltage for each respective frame may be set based on the duration of each respective blank period.
