Beschreibung
Zusammenfassung:	The present invention relates to: a polyimide precursor resin composition which has a low thermal expansion coefficient, is not subject to clouding during solution casting, has excellent high-transparency as well as excellent light characteristics and phase retardation characteristics; a method for manufacturing a polyimide film using same; and a polyimide film manufactured thereby. The present invention can be useful in a flexible display substrate material and a semiconductor material. La présente invention concerne : une composition de résine précurseur de polyimide qui a un faible coefficient de dilatation thermique, n'est pas soumise à la turbidité pendant la coulée en solution, a une excellente transparence élevée ainsi que des caractéristiques lumineuses et des caractéristiques de retard de phase excellentes ; un procédé de fabrication d'un film de polyimide l'utilisant ; et un film de polyimide ainsi fabriqué. La présente invention peut être utile dans un matériau de substrat d'affichage souple et un matériau semi-conducteur. 본 발명은 낮은 열팽창 계수를 갖으며, 용액 캐스팅 시 백탁 현상이 발생하지 않으며, 우수한 고투명성을 갖으면서도 광 특성 및 위상 지연 특성이 우수한 폴리이미드 전구체 수지 조성물, 이를 이용한 폴리이미드 필름 제조방법, 및 이에 의해 제조된 폴리이미드 필름에 관한 것으로, 플렉서블 디스플레이 기판 소재, 반도체 소재에 유용하게 활용될 수 있다.
