Claim 6:
7. A driving circuit 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 for controlling the operation of the driving transistor, the driving circuit comprising:
a shift register configured to generate a first output signal through a first node and a second output signal through a second node depending on a stabilization start pulse;
a buffer circuit configured to transmit an initialization voltage to a first output terminal, and a bias voltage and a leakage suppression voltage to a second output terminal depending on the first output signal and the second output signal; and
a switching circuit configured to supply the bias voltage or the leakage suppression voltage to a source electrode of the driving transistor depending on a selection signal.
