1. A display device comprising:
a display panel including a pixel;
a gate driver which applies an anode initialization signal to the pixel; and
a driving controller which receives a horizontal synchronization signal, receives input image data at a variable frame frequency, and controls the gate driver,
wherein a frame period for the display panel includes a scan period or one or more hold periods,
wherein the driving controller generates a count value by counting a number of pulses of the horizontal synchronization signal, and determines a current frame period as a hold period when the count value exceeds a reference value, and
wherein a time length of the anode initialization signal in each of the one or more hold periods is longer than a time length of the anode initialization signal in the scan period.
