Patent ID: 11600677

Abstract:
A thin film transistor (TFT) array substrate for an electronic device includes a first active layer of a first TFT which is an oxide semiconductor layer including molybdenum, a second active layer of a second TFT which is an oxide semiconductor layer and disposed on a buffer layer to be spaced apart from the first active layer of the first TFT, a first gate insulating film overlapping the first active layer and the second active layer, a first gate electrode of the first TFT overlapping the first gate insulating film and a part of the first active layer, and a second gate electrode of the second TFT overlapping the first gate insulating film, spaced apart from the first gate electrode, and overlapping a part of the second active layer. Accordingly, the first TFT has a high subthreshold parameter, and the second TFT has high mobility.
