1. A pixel that operates at a first scanning rate in a first mode and operates at a second scanning rate in a second mode, the pixel comprising:
a display element having an anode and a cathode;
a first transistor that controls a magnitude of a driving current flowing to the display element according to a gate-source voltage; and
a second transistor that is in an off state during all frame periods in the first mode and transmits a bias voltage to the first transistor in response to a first scan signal in the second mode.
