A display device includes a driving controller sensing a pattern of first image signals from a source external to the driving controller and outputting a compensation selection signal corresponding to the sensed pattern. A voltage generator generates a driving power voltage in response to the compensation selection signal. The voltage generator includes a power converter generating the driving power voltage in response to a power control signal, a comparator comparing the driving power voltage with a reference voltage to output a feedback signal to a first node, and a compensation circuit including a plurality of compensation units. A selected compensation unit is connected to the first node, and a power control circuit outputs the power control signal in response to the feedback signal. The slew rate of the feedback signal may be controlled by a compensation circuit to remove a ripple component from the driving power voltage.
