摘要： Provide is a polar compound having high chemical stability, high capability of aligning liquid crystal molecules, high solubility in a liquid crystal composition, and a large voltage holding ratio when the compound is used in a liquid crystal display device. The problem is solved by a compound represented by formula (1). For example, R1 is alkyl having 1 to 15 carbons; rings A1 to A5 are cyclohexylene or phenylene; Z1, Z4 and Z5 are a single bond or alkylene having 1 to 10 carbons; a, b and c are 0 to 4; d and e are 1 to 4; P2 and P3 are a polymerizable group; and Sp2 and Sp3 are a single bond or alkylene having 1 to 10 carbons.
