Abstract:
A reverse dispersion retardation film is formed by stretching a film containing a norbornene-based ring-opening copolymer containing a structural unit (A) represented by a general formula (1) and a structural unit (B) represented by a general formula (2), wherein a total amount of the structural unit (A) and an exo-form structural unit, among the structural units (B), is not less than 20 mol % but not more than 65 mol % of all the structural units.
