Disclosed is a polymerizable liquid crystal compound having a wide temperature range of a liquid crystal phase, excellent compatibility with other compounds, and further having necessary characteristics such as optical anisotropy. A polymerizable liquid crystalline compound represented by formula (1) or formula (2). R a —Z— (AZ) m —R b (1), R a —Z— (AZ) m—R a (2) [R a is a polymerizable group such as an acryloyloxy group; R b Is H or a C1-12 alkyl group in which any —CH 2 — in the alkyl group may be replaced by —O—, —CO—, —COO—, or —OCO—; A has a substituent 1,4-phenylene group and the like which may be present; Z is a single bond, — (CH 2 ) n —, —O (CH 2 ) n —, — (CH 2 ) n O—, —O (CH 2 ) n O-, -CH = CH-, -C≡C-, -COO-, etc .; n is an integer of 1 to 10; m is an integer of 1 to 6] [Selection figure] None |
