Abstract
A thin film transistor, which is capable of improving carrier mobility, and a display device and an electronic device, each of which uses the thin film transistor, are provided. The thin film transistor includes: a gate electrode; an oxide semiconductor layer including a multilayer film including a carrier travel layer configuring a channel and a carrier supply layer for supplying carriers to the carrier travel layer; a gate insulating film provided between the gate electrode and the oxide semiconductor layer; and a pair of electrodes as a source and a drain. A conduction band minimum level or a valence band maximum level corresponding to a carrier supply source of the carrier supply layer is higher in energy than a conduction band minimum level or a valence band maximum level corresponding to a carrier supply destination of the carrier travel layer.
