Abstract
A method of applying an OFF-state offset to a display device includes: supplying a ground voltage from a data driving circuit; to a source electrode of a thin film transistor supplying a gate voltage from a gate driving circuit to a gate electrode of the thin film transistor, the gate voltage turning off the thin film transistor; and supplying an AC voltage to a drain electrode of the thin film transistor.
