Claim 11:
12. A display driving method of a display panel including a light emitting element, a driving transistor providing a driving current to the light emitting element using a driving voltage, and a plurality of switching transistors controlling the operation of the driving transistor, comprising:
switching from a first mode driven at a higher driving frequency to a second mode driven at a lower driving frequency;
supplying an initialization voltage with a negative level to a driving transistor in an initialization period;
supplying a bias voltage with a first positive level to the driving transistor in a bias period; and
supplying a leakage suppression voltage with a second positive level different from the first positive level to the driving transistor in a leakage suppression period including an emission period.
