1. A liquid crystal composition comprising:
a liquid crystal compound A represented by Formula (I);
a compound B represented by Formula (II); and
a dichroic substance,
wherein a ratio of a mass of the compound B to a mass of the liquid crystal compound A is in a range of 0.001 to 0.04,
Q1-V1-SP1-X1-(Ma-La)na-X2-SP2-V2-Q2  (I)
Q1-V1-SP1-X1-(Mb-Lb)nb-SP3-(Mc-Lc)nc-X2-SP2-V2-Q2  (II)
in Formulae (I) and (II),
Q1 and Q2 each independently represent a polymerizable group,
V1, V2, X1, and X2 each independently represent a single bond or a divalent linking group,
SP1 and SP2 each independently represent a divalent spacer group,
SP3 represents a divalent linear spacer group having three or more atoms constituting a main chain of a bonding site and two or more and 25 or less carbon atoms,
na, nb, and nc each independently represent an integer of 2 to 10,
Ma, Mb, and Mc each independently represent an aromatic ring, an aliphatic ring, or a heterocyclic ring which may have a substituent, where a plurality of Ma's may be the same as or different from each other, a plurality of Mb's may be the same as or different from each other, and a plurality of Mc's may be the same as or different from each other,
La represents a single bond or a divalent linking group, where a plurality of La's may be the same as or different from each other, and in a case where La present between Ma and Ma represents a divalent linking group, a divalent linking group consisting of a divalent linear spacer group having three or more atoms constituting a main chain of a bonding site and two or more carbon atoms is excluded, and
Lb and Lc each independently represent a single bond or a divalent linking group, where a plurality of Lb's may be the same as or different from each other, and a plurality of Lc's may be the same as or different from each other.
