Abstract:
1. A thin film transistor substrate, comprising: a substrate; a first thin film transistor disposed on the substrate, the first thin film transistor comprising: a gate insulating layer covering the polycrystalline semiconductor layer; a second thin film transistor disposed on the substrate over the gate insulating layer, the second thin film transistor comprising: an intermediate insulating layer comprising a nitride layer and disposed on the first gate electrode; and an oxide layer covering the second gate electrode and disposed on the intermediate insulating layer, wherein the oxide semiconductor layer is disposed on the oxide layer and overlaps the second gate electrode, wherein the first source electrode, the first drain electrode, and the second gate electrode are disposed between the intermediate insulating layer and the oxide layer, wherein the second source electrode and the second drain electrode are disposed on the oxide semiconductor layer, wherein a gate line is disposed between the gate insulating layer and the intermediate insulating laver, and wherein a data line and the second gate electrode are disposed between the intermediate insulating layer and the oxide laver.
