Provided is a polyimide-containing polymer capable of simultaneously maintaining good light transmittance, flexibility, and heat durability. A polyimide-containing polymer comprising units represented by formula (I), formula (II), and formula (III). [A is an aromatic group having fluorine; B, B ′ and B ″ are each independently an aromatic group; B / (B + B ′ + B ″), B ′ / (B + B ′ + B ″) and B ″ / (B + B ′ + B ″) is greater than zero. The polyimide film having it has high transparency, high heat resistance and good flexibility, and is almost colorless and transparent, so that different kinds of colorants can be mixed in the thin film layer, resulting in polyimide The film may exhibit different colors in this and some embodiments] [Selection figure] None |
