METHOD FOR MANUFACTURING A THIN FILM TRANSISTOR

A thin-film transistor, a method for manufacturing the same and a display device including the same are provided. The thin-film transistor may include a substrate, and an active layer formed on the substrate. The active layer may be made from an oxide semiconductor. A gate electrode may be formed above the active layer or below the active layer. A conductive layer may come in contact with the active layer, may be overlapped with at least a part of the gate electrode, and may be insulated from the gate electrode. A source electrode and a drain electrode may be electrically connected to the active layer. The conductive layer can reduce a channel length of the thin-film transistor and increase a capacitance between the source electrode and the gate electrode or between the drain electrode and the gate electrode.
