Claim 11:
12. A display device comprising:
a display panel including a plurality of pixels configured to display an image at one of a plurality of different refresh frequencies, the plurality of different refresh frequencies including a first refresh frequency and a second refresh frequency that is different from the first refresh frequency;
a data driver configured to apply data voltages to the plurality of pixels; and
a gate driver configured to apply scan signals to the plurality of pixels,
wherein at least one of the plurality of pixels includes:
a driving element including a gate electrode of the driving element that is connected to a first node, a first electrode of the driving element that is connected to a second node to which a data voltage from the plurality of data voltages is applied, and a second electrode of the driving element that is connected to a third node;
a light emitting element configured to emit light by being driven by a current from the driving element; and
a first switch element configured to supply a bias voltage from a power line to the third node that is connected to the second electrode of the driving element while the light emitting element does not emit light,
wherein a frequency at which the bias voltage is supplied to the third node during the first refresh frequency is a same as a frequency at which the bias voltage is supplied to the third node during the second refresh frequency.
