Abstract
A novel liquid crystal composition that can be used for a variety of liquid crystal devices is provided. A stable liquid crystal element that is driven at low voltage and that withstands physical impact is provided with the use of the novel liquid crystal composition. A highly reliable liquid crystal display device with low power consumption and high display quality is provided with the use of the liquid crystal element. The liquid crystal composition exhibits a blue phase and contains nematic liquid crystal, 1,4:3,6-dianhydro-2,5-bis[4-(n-hexyl-1-oxy)benzoic acid]sorbitol (abbreviation: ISO-(6OBA)) represented by the structural formula (100) as a first chiral agent, and (4R,5R)-4,5-bis[hydroxy-di(phenanthren-9-yl)methyl]-2,2-dimethyl-1,3-dioxolane (abbreviation: R-DOL-Pn) represented by the structural formula (101) as a second chiral agent.
