Beschreibung
Zusammenfassung:	The present invention relates to a polyimide-based polymer film, and a substrate for a display device and an optical device, each using the same, wherein the polyimide-based polymer film is synthesized by a reaction between specifically structured acid anhydride compounds and diamine compounds, and thus can secure excellent optical characteristics even in conditions of high-temperature thermal treatment and can stably maintain optical characteristics even at additional thermal treatment. 본 발명은 특정 구조의 산무수물 화합물과 디아민 화합물의 반응으로 합성되어, 고온의 열처리 조건에서도 우수한 광학 특성을 확보할 수 있고, 추가열처리 시에도 광학 특성이 안정적으로 유지될 수 있는 폴리이미드계 수지 필름 및 이를 이용한 디스플레이 장치용 기판, 및 광학 장치에 관한 것이다.
