The fabrication method includes: forming a gate electrode, an active layer, a drain electrode and a source electrode on the base substrate, in which the active layer includes a channel region and a second portion on both sides of the channel region, and at least a portion of the channel region is overlapped with the gate electrode; and performing a laser annealing process on a side of the base substrate by using a laser, in which the channel region is shielded without being irradiated by the laser, a resistivity of the second portion of the active layer is lower than a resistivity of the channel region, and the second portion of the active layer is connected with the source electrode and the drain electrode. A thin film transistor, an array substrate and a display device are further provided."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Thin film transistor and fabrication method thereof, array substrate and display device","description":"A fabrication method of a thin film transistor is provided.
