Abstract
The present disclosure relates to a thin-film transistor including two-dimensional semiconductor and display apparatus including the same. The thin-film transistor includes a gate electrode disposed on a substrate, a semiconductor layer disposed so as to overlap at least a portion of the gate electrode in the state of being isolated from the gate electrode, a gate insulation film disposed between the gate electrode and the semiconductor layer, a source electrode connected to the semiconductor layer, and a drain electrode connected to the semiconductor layer in the state of being spaced apart from the source electrode, wherein the semiconductor layer includes a first layer including an oxide semiconductor and a second layer disposed so as to overlap the first layer in a plane view, the second layer comprising a two-dimensional semiconductor, and an energy band gap of the first layer is larger than an energy band gap of the second layer.
