Abstract: A thin film transistor, a method for manufacturing the same and a display device are provided in the present disclosure. The thin film transistor includes an active layer, a first electrode and a second electrode, and a gate electrode. The active layer includes an active layer body and an electrode hole in a center of the active layer body. The gate electrode is insulated and spaced apart from the active layer body and is disposed to surround the electrode hole. The first electrode and the second electrode are insulated from each other, both coupled to the active layer body, and insulated and spaced apart from the gate electrode. At least a portion of an orthographic projection of the first electrode on the active layer is within the electrode hole. An orthographic projection of the second electrode on the active layer surrounds the active layer body.
