DIAMINE AND USE THEREOF

WIPO Patent Application WO/2017/122730

A1

[Problem] To provide a novel diamine that produces a film having excellent flexibility and transparency and also having low retardation characteristics. [Solution] Disclosed are: a diamine characterized by being represented by formula (1-1); a polyamic acid and a polyimide obtained from said diamine; a film-forming composition including said polyimide; and a film and a flexible-device substrate which are formed therefrom. [Chem. 1] (In the formula, X represents an oxygen atom or a -NH- group, Y represents a halogen atom, a C1-5 alkyl group, a C1-5 haloalkyl group, or a C1-5 alkyl group, and n represents an integer from 0 to 4.)
