Abstract

The invention provides a thin film transistor comprising an active layer, the active layer comprising an IGZO-based oxide material, the IGZO-based oxide material being represented by a composition formula of In2-xGaxZnO4-δ, where 0.75<x<1.10 and 0<δ≦1.29161×exp(−x/0.11802)+0.00153 and being formed from a single phase of IGZO having a crystal structure of YbFe2O4, and a method of producing the thin film transistor.
