Zusammenfassung:	Provided are a diamine compound represented by chemical formula 1, a polyamic acid and polyimide manufactured from the same, and a polyimide film. The diamine compound according to an embodiment contains a plurality of ether and sulfone groups. Therefore, it is structurally very flexible and has high chemical stability. 하기 화학식 1로 표시되는 디아민 화합물, 이로부터 형성된 폴리아믹산, 폴리이미드 및 폴리이미드 필름이 제공된다.[화학식 1]화학식 1 중, A는 -S(=O)- 또는 -S-이고, Ar및 Ar는 각각 독립적으로 하기 화학식 1-1 내지 1-3으로 이루어지는 그룹으로부터 선택되고, [화학식 1-1] [화학식 1-2] [화학식 1-3]상기 화학식 1-1내지 1-3 중, R내지 R는 각각 독립적으로 수소, 탄소수 1 내지는 30의 알킬기 및 트리플루오로메틸(CF3)로 이루어지는 그룹으로부터 선택되며, *는 결합 영역을 나타낸다.
