Polymerizable composition comprising a polymerizable compound, a half mirror film, and a projected image display

The present invention, as a low birefringence polymerizable composition formula (I): In the formula, A represents a phenylene group or a trans-1,4-cyclohexylene group, L is -OC (= O) -, - indicates OC (= O) O-, etc., m represents 3 to 12, sp By using the polymerizable composition, it is possible to provide a film such as low birefringence phase difference film or a high selectivity for reflection wavelength band reflective film.
