Abstract
A cholesteric liquid crystal composition containing at least one esterified product selected from the group consisting of (1) an esterified product of a hydrolysate of (A) a γ-oryzanol and (B1) a carboxylic acid compound, (2) an esterified product of a hydrogenated product of a hydrolysate of (A) a γ-oryzanol and (B2) a carboxylic acid compound, and (3) an esterified product of a hydrogenated product of (A) a γ-oryzanol and (B3) a carboxylic acid compound. The γ-oryzanol (A) is a mixture containing at least one ferulate ester of a vegetable sterol and at least one ferulate ester of a triterpene alcohol, and the hydrolysate of the γ-oryzanol (A) is a mixture containing at least one vegetable sterol and at least one triterpene alcohol.
