A liquid-crystal material containing a cellulose derivative having a molecular structure represented by general formula (1A). In general formula (1A), X11, X12, and X13 each independently represent a single bond, an alkylene group, -(R14-O)h-, or-C(=O)-R15-; R11, R12, and R13 each independently represent a hydrogen atom, a group having an unsaturated double bond, or a hydrophobic group; R14 and R15 each independently represent an alkylene group; h represents an integer of 1-10; and n11 represents an integer of 2-800. However, at least one of R11, R12, and R13 represents a group having an unsaturated double bond represented by general formula (3C) and/or a C5-20 linear or branched acyl group. |
