Claim 0:
1. A liquid crystal composition comprising:
a high-molecular weight liquid crystal compound; and
a dichroic substance,
wherein the high-molecular weight liquid crystal compound is a copolymer having a repeating unit (1) represented by Formula (1) and a repeating unit (2) represented by Formula (2),, in Formula (1), P1 represents a main chain of the repeating unit, L1 represents a single bond or a divalent linking group, SP1 represents a spacer group, M1 represents a mesogenic group, and T1 represents a terminal group,, in Formula (2), P2 represents a main chain of the repeating unit,
in Formula (2), L2 represents a single bond, a divalent alicyclic group which may have a substituent, or a divalent aromatic group which may have a substituent,
in Formula (2), SP2 represents an alkylene group having 10 or more atoms in the main chain, where one or more pieces of —CH2— constituting an alkylene group represented by SP2 may be substituted with at least one group selected from the group consisting of —O—, —S—, —N(R21)—, —C(═O)—, —C(═S)—, —C(R22)═C(R23)—, an alkynylene group, —Si(R24)(R25)—, —N═N—, —C(R26)═N—N═C(R27)—, —C(R28)═N—, and —S(═O)2—, R21 to R28 each independently represent a hydrogen atom, a halogen atom, a cyano group, a nitro group, a linear alkyl group having 1 to 10 carbon atoms or a branched alkyl group having 3 to 10 carbon atoms, and hydrogen atoms contained in the one or more pieces of —CH2— constituting an alkylene group represented by SP2 may be substituted with at least one group selected from the group consisting of a halogen atom, a cyano group, a nitro group, a hydroxyl group, a linear alkyl group having 1 to 10 carbon atoms, and a branched alkyl groups having 3 to 10 carbon atoms, and
in Formula (2), T2 represents a hydrogen atom, a methyl group, a hydroxyl group, a carboxy group, a sulfonic acid group, a phosphoric acid group, a boronic acid group, an amino group, a cyano group, a nitro group, a vinyl group, an acryloyloxy group, a methacryloyloxy group, an epoxy group, an epoxycycloalkyl group, a maleimide group, an oxetanyl group which may have a substituent, or a phenyl group which may have at least one substituent selected from the group consisting of a boronic acid group, a sulfonic acid group, a vinyl group and an amino group.
