Abstract

The present invention provides an oxide semiconductor that realizes a TFT excellent in electric properties and process resistance, a TFT comprising a channel layer formed of the oxide semiconductor, and a display device equipped with the TFT. The oxide semiconductor of the present invention is an oxide semiconductor for a thin film transistor, wherein the oxide semiconductor contains Ga (gallium), In (indium), Zn (zinc), and O (oxygen) as constituent atoms, and the oxide semiconductor has Zn atomic composition satisfying the equation of 0.01≦Zn/(In+Zn)≦0.22.
