    Abstract: A method for forming low-temperature polysilicon thin film, a thin film transistor and a display device are provided. The method for forming low-temperature polysilicon thin film comprises: depositing an amorphous silicon thin film on a base substrate; covering the amorphous silicon thin film with an anti-reflective optical film; performing photolithography and etching on the anti-reflective optical film such that light condensing structures are provided in an array on the anti-reflective optical film; and irradiating the amorphous silicon thin film with the anti-reflective optical film covered by laser light such that the amorphous silicon film is converted into the low-temperature polysilicon thin film. The method may improve the grain size and uniformity of the low-temperature polysilicon thin film, make full use of the energy of the incident laser light, facilitate the reduction of the production cost of the low-temperature polysilicon thin film, and improve the performance of the low-temperature polysilicon thin film transistor.
