Classification: CPC G | IPC G

Claim 0:
1. A display device comprising:
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 configured to control the operation of the driving transistor;
a gate driving circuit configured to supply a plurality of scan signals to the display panel through a plurality of gate lines;
an emission driving circuit configured to supply a plurality of emission signals to the display panel through a plurality of emission signal lines;
a data driving circuit configured to supply a data voltage to the display panel; and
a timing controller configured to control a leakage suppression voltage to be supplied to the driving transistor in a leakage suppression period after a bias voltage is supplied to the driving transistor in a low speed mode in which the display panel is driven at a lower driving frequency,
wherein the low speed mode includes:
a refresh frame in which the data voltage configured to drive the light emitting element is supplied; and
a skip frame in which the data voltage is not supplied,
wherein the leakage suppression period includes the emission period in which the light emitting element emits light between the refresh frame and the skip frame.
