Abstract

A polar compound has a high chemical stability, high ability to align liquid crystal molecules and high solubility in a liquid crystal composition, and causes no decrease of liquid crystallinity of the liquid crystal composition, a liquid crystal composition contains the compound, and a liquid crystal display device includes the composition. The compound is represented by formula (1), the composition contains the compound, and the liquid crystal display device uses the composition. In formula (1), Ris alkyl having 3 to 15 carbons, alkenyl having 4 to 15 carbons or the like; a is an integer from 2 to 12; and Ris a group represented by formula (1a), formula (1b) or formula (1c). In the formulas, Sand Sare independently a single bond, alkylene having 1 to 10 carbons; Sis >CH— or >N—; Sis >C< or >Si<; and Xis —OH, —NHor the like.
