Abstract: A display device can operate in a first mode for displaying at least a first image including first frames based on a first driving frequency, or in a second mode for displaying a second image including second frames based on a second driving frequency different from the first driving frequency. Further, when the first image displayed on the display panel operating in the first mode is changed to a third image, at least one frame among third frames running after the first image has been displayed among the plurality of frames displaying the third image operates at the second driving frequency based on the second mode. Also, in the first mode, the second image includes reset frames for periodically resetting a voltage of an anode electrode between refresh frames for supplying at least one data signal to at least one of the plurality of pixels for a preset time.
