Abstract:
1. A thin film transistor, comprising: a first gate electrode; an active layer comprising a crystalline oxide semiconductor layer being insulated from the first gate electrode by a first insulating layer, the active layer being arranged to overlap the first gate electrode; a source electrode and a drain electrode spaced apart from the source electrode; a second insulating layer; and a second gate electrode, the second gate electrode and the first gate electrode being arranged on opposite sides of the active layer, wherein the second gate electrode is insulated from the active layer by the second insulating layer, wherein the active layer comprises a triple layer comprising a first crystalline oxide semiconductor layer, an amorphous oxide semiconductor layer, and a second crystalline oxide semiconductor layer, and wherein the first crystalline oxide semiconductor layer is arranged adjacent to the first insulating layer, and the second crystalline oxide semiconductor layer is arranged adjacent to the second insulating layer.
