Summary: | PROBLEM TO BE SOLVED: To provide a resin composition which forms a cured film having a high refractive index, being excellent in transparency and further excellent also in heat resistance and mainly composed of an imidized polymer having a specific structure. SOLUTION: The resin composition comprises one or more kinds of polyamic acids having structures represented by general formula (3) wherein R is a tetravalent organic group; R1are each independently a 1-3C alkyl group; (a) are each independently an integer of 0-4; (b) are each independently an integer of 0-3; m is 1-100,000 and (E) an organic solvent.
