Abstract:
1. A thin-film transistor (TFT), comprising: a gate electrode disposed on a substrate; an insulating layer disposed on the substrate and the gate electrode; an active layer pattern disposed on the insulating layer, the active layer pattern overlapping the gate electrode; a source electrode disposed on the insulating layer and overlapping at least part of the active layer pattern; a drain electrode disposed on the insulating layer, spaced apart from the source electrode, and overlapping at least part of the active layer pattern; and a first ohmic contact layer pattern disposed between the active layer pattern and the source electrode and between the active layer pattern and the drain electrode, wherein the first ohmic contact layer comprises a nitride layer and a non-nitride layer, the nitride layer being disposed on the non-nitride layer within the first ohmic contact layer.
