Abstract
The present invention provides an oxide semiconductor capable of achieving a thin film transistor having stable transistor characteristics, a thin film transistor having a channel layer formed of the oxide semiconductor and a production method thereof, and a display device equipped with the thin film transistor. The oxide semiconductor of the present invention is an oxide semiconductor for a thin film transistor. The oxide semiconductor includes indium, gallium, zinc, and oxygen as constituent atoms, and the oxygen content of the oxide semiconductor is 87% to 95% of the stoichiometric condition set as 100%, in terms of atomic units.
