1. A pixel circuit comprising:
a driving transistor including a first electrode connected to a first node, a gate electrode connected to a second node, and a second electrode connected to a third node, the driving transistor configured to supply a driving current to a light emitting device;
a first transistor that is electrically connected between the second node and the third node;
a second transistor that is electrically connected between the first node and a data line that supplies a data voltage;
a third transistor that is electrically connected between the first node and a power line that supplies a high potential voltage;
a storage capacitor which comprises a first electrode and a second electrode, the first electrode of the storage capacitor connected to the power line that supplies the high potential voltage and the second electrode of the storage capacitor connected to the second node; and
a seventh transistor electrically connected between the first node and a second voltage line that supplies a bias voltage,
wherein the first transistor and the second transistor receive a first scan signal, and the first transistor is configured to electrically connect the second electrode of the driving transistor to the gate electrode of the driving transistor responsive to the first scan signal, and the second transistor is configured to supply the data voltage to the first electrode of the driving transistor responsive to the first scan signal.
