Abstract
Embodiments of the disclosure provide a thin film transistor and a fabrication method thereof, an array substrate and a display. The thin film transistor comprises a gate electrode, a gate insulating layer, an active layer, a source electrode and a drain electrode. The active layer comprises a first active layer and a second active layer; and the first active layer is arranged close to the gate insulating layer, and the second active layer is arranged close to the source electrode and the drain electrode. A carrier mobility of the first active layer is greater than that of the second active layer.
