Abstract
Provided are a polymerizing liquid-crystalline compound of formula (1). In formula (1), Qto Qeach independently represent a formula (2), a hydrogen atom, a halogen atom, an alkyl group or the like; at least two of Qto Qare a formula (2) and may differ from each other. In formula (2), A independently represent a 1,4-cyclohexylene group, a 1,4-phenylene group or the like; X independently represents a single bond, an alkylene group or the like; Z represents a single bond, —COO—, —OCO— or the like; n indicates an integer of from 0 to 3; p represents any one polymerizing group of formulae (P1) to (P8); W represents a hydrogen atom, a halogen atom, an alkyl group or the like. When Qand Qare both hydrogen atoms and when Qand Qare both formula (2), then p must not be (P8).
