The present invention provides a thin film transistor, a fabricating method thereof, a display substrate and a display device. In the fabricating method, a protective layer and an oxide active layer are patterned by one patterning process, to form patterns of the protective layer and the oxide active layer; and annealing is performed in an oxygen-containing atmosphere, so that the material of the oxide active layer diffuses into the protective layer through a contact surface between the oxide active layer and the protective layer, to form a transitional region in the protective layer, and the material of the protective layer diffuses into the oxide active layer through the contact surface, to form a transitional region in the oxide active layer, the transitional regions are configured to reduce an off-state current of the thin film transistor.
