Abstract
A method of preparing a thin film and a method of manufacturing a display device are disclosed. The method of preparing a thin film includes the following steps: providing a substrate having a film formation region and a non-film formation region surrounding the film formation region; forming a gas precursor repellent layer in the non-film formation region; and depositing a gas precursor on the film formation region by atomic deposition to form the film. The method of preparing a film and the method of manufacturing a display device of the present invention can effectively achieve the effect of limiting the boundary of the film by forming the gas precursor repellent layer in the non-film formation region, and finally eliminate the problem of boundary epitaxial caused by atomic deposition.
