| titleOfInvention | Polyimide precursor composition, polyamic acid, polyimide resin, polyimide film and optical device |
| abstract | [Problem] A polyimide precursor composition which provides a polyimide film having a high refractive index and low retardation, a polyamic acid suitable as a precursor component in the polyimide precursor composition, and the polyimide precursor composition described above can be produced. It is providing the optical device provided with the polyimide resin, the polyimide film which can be manufactured using the polyimide precursor composition mentioned above, and the polyimide film mentioned above. [Solution] An aromatic diamine compound having two amino group-containing aromatic groups bonded to a specific structure on the same carbon atom in a polycyclic skeleton such as a fluorene skeleton is contained in the resin precursor component (B) as the diamine component (B1); And using a polyamic acid (B3) containing a structural unit having a structure derived from the aromatic diamine compound of the above-mentioned specific structure as a resin precursor component (B), a polyimide resin or a polyimide film is formed. |
