Zusammenfassung:	The present invention relates to a polyimide precursor composition, and a polyimide film manufactured using same. According to the present invention, since a polyimide film is manufactured from a mixture of a polyimide precursor having a structure that is advantageous to surface charge accumulation and a polyimide precursor having a structure capable of exhibiting high heat-resistant characteristics, a flexible device using the polyimide film as a substrate can have both improved charge accumulation characteristics caused by an electric field to be generated during the operation of a TFT device and heat high heat-resistant characteristics.
