The present invention provides a polyimide-based composition for a display and a polyimide-based film excellent in ultraviolet stability and prepared by using the same. Provided is a polyimide-based film comprising: a polyimide or polyamide-imide copolymer; and more than one light stabilizer selected from the group consisting of a 2-hydroxyphenylbenzotriazole derivative, a 2-hydroxyphenyltriazinederivative, a hindered amine derivative, and a mixture thereof. The light stabilizer accounts for 0.01 to 6 parts by weight with respect to 100 parts by weight of the polyimide or polyamide-imide copolymer.
