[과제] 내열성이 우수하고, 리타데이션이 낮으며, 유연성이 우수하고, 나아가 투명성도 우수하다고 하는 우수한 성능을 유지함과 함께, 지지기재나 그 위에 형성된 박리층으로부터 용이하게 박리할 수 있는 플렉서블 디스플레이기판 등의 플렉서블 디바이스기판의 베이스필름으로서 우수한 성능을 갖는 플라스틱박막을 부여하는 수지조성물을 제공하는 것을 목적으로 한다. [해결수단] 하기 (A)성분, (B)성분 및 (C)성분을 포함하는 것을 특징으로 하는 유기무기하이브리드 수지조성물. (A)성분: 탄소원자수 6 내지 18의 방향족기를 2개 가지거나 또는 탄소원자수 7 내지 18의 방향족기를 1개 갖는 알콕시실란 화합물로 미립자표면을 수식한, 평균입자경 1nm 내지 100nm의 무기미립자, (B)성분: 불소를 갖는 폴리이미드, (C)성분: 유기용매. [Problem] The purpose of the present invention is to provide a resin composition for providing a plastic thin film that maintains excellent properties such as excellent heat resistance, low retardation, excellent flexibility, and excellent transparency, and that has excellent properties as a base film of a flexible device substrate such as a flexible display substrate that can be easily de-bonded from a support base material or a de-bonding layer formed on the support base material. [Solution] This organic/inorganic hybrid resin composition is characterized by containing component (A), component (B), and component (C). Component (A): inorganic fine particles having an average particle size of 1-100 nm and having a surface modified with an alkoxy silane compound having two aromatic groups having 6-18 carbon atoms or one aromatic group having 7-18 carbon atoms. Component (B): a polyimide having fluorine. Component (C): an organic solvent.
