A composition includes a polymerizable liquid crystal compound (A), a photopolymerization initiator (B), and a crosslinking agent (C), and satisfies:
|λ
a1
−λ
b1
|≤20 nm (i), and
λ
c1
≤250 nm (ii),
where λ
a1
represents a wavelength of an absorption local maximum that is the longest one of wavelengths of absorption local maxima in a light absorption spectrum of from 200 nm to 500 nm of the polymerizable liquid crystal compound (A), λ
b1
represents a wavelength of an absorption local maximum that is the longest one of wavelengths of absorption local maxima in a light absorption spectrum of from 200 nm to 500 nm of the photopolymerization initiator (B), and λ
c1
represents a wavelength of at least one absorption local maximum in a light absorption spectrum of from 200 nm to 500 nm of the crosslinking agent (C)).
