Abstract
A method of manufacturing a low temperature polysilicon thin film, including the steps of: forming a buffer layer on a substrate; forming a silicon layer on the buffer layer; roughening a surface of the silicon layer to form an uneven surface as a recrystallization growth space; and annealing the silicon layer to form a polysilicon layer, and a partial silicon material of the polysilicon layer is formed on the recrystallization growth space.
