Abstract: Disclosed is a polymerizable compound useful for preparing a polymer that enables the production of a film, such as an optical film, which has a good balance of lightness and saturation and which can improve reverse wavelength dispersion on the short wavelength side while achieving reverse wavelength dispersion on the longer wavelength side. The polymerizable compound of the present disclosure is represented by: where in the formula (I-1), A1 and A2 each independently represent an aromatic group which may have a substituent, B1 and B2 each independently represent a cyclic aliphatic group which may have a substituent, or, an aromatic group which may have a substituent, and p and q each independently represent an integer from 0 to 2.
