Abstract: A display device includes a display panel receiving an emission driving signal, and a panel driver driving the display panel in a mode in which the driving frequency is varied. The panel driver includes an emission driving circuit outputting the emission driving signal, a data driving circuit outputting a data signal, and a driving controller. The data driving circuit inverts a polarity of the data signal in units of at least one driving frame in response to a first option signal. The driving controller includes a counting circuit which counts an operation cycle of the emission driving circuit to output a count value, and a first option control circuit which compares the count value with a preset first threshold value and sets the first option signal to an active state or an inactive state according to a comparison result.
