An optical film capable of performing uniform polarization conversion in a wide wavelength range. An optical film composition containing cyclopentanone or cyclohexanone and a compound containing a group represented by the formula (A) and a polymerizable group. -G a -D a -Ar a -D b -G b - (A) [ in the formula (A), at least one aromatic ring Ar a is selected from the group consisting of an aromatic hydrocarbon ring and an aromatic heterocyclic represents a divalent group having, D a and D b are each independently a single bond, -CO-O -, - O -CO -, - C (= S) -O -, - O-C ( = S) -, - CR1R 2 -, represents, G a and G b each independently represents a divalent alicyclic hydrocarbon group. ] [Selection figure] None |
