Abstract
Embodiments of the present invention disclose a thin film transistor and an array substrate, manufacturing methods thereof, and a display device, which relate to the field of display technology, and can improve drifting of a threshold voltage of a thin film transistor and enhance the stability and reliability of an array substrate. The thin film transistor comprises an active layer and a gate insulating layer, wherein the material of the active layer is a metal oxide semiconductor, and during forming the thin film transistor, the gate insulating layer conveys oxygen to the active layer so as to reduce an interface state density and a movable impurity concentration of a contact interface between the active layer and the gate insulating layer.
