Abstract: A polyimide precursor monomer having an E value of 2.0 or more calculated by Equation 1 is selected among polyimide raw materials. A polyimide includes a structural unit derived from the polyimide precursor monomer having the E value of 2.0 or more. Optical properties of a polyimide film formed from the polyimide can be improved, and the optical properties of a polyimide film can be predicted from the E value of the polyimide precursor monomer even before production of the polyimide film.
