Zusammenfassung:	Disclosed are a polyimide precursor composition that can be used in the manufacture of flexible substrates, a method for manufacturing a polyimide film using the same and a display device including the polyimide film. The polyimide precursor composition may include a mixed solvent including 1-ethyl-2-pyrrolidone and N,N-dimethylpropionamide; and polyamic acid or polyimide. 플렉서블 기판의 제조에 사용될 수 있는 폴리이미드 전구체 조성물, 이를 이용한 폴리이미드 필름 제조방법 및 폴리이미드 필름을 포함하는 디스플레이 소자가 개시된다. 상기 폴리이미드 전구체 조성물은 1-에틸-2-피롤리돈과 N,N-디메틸프로피온아미드를 포함하는 혼합 용매; 및 폴리아믹산 또는 폴리이미드를 포함한다.
