摘要：
A ferroelectric liquid crystal composition having high speed response properties and exhibiting SC * phase within a broad temperature range including room temperature and a light-switching element using the composition are provided, which composition comprises the following components, A, B and C, each in a specified proportion:
Component A has the formula
wherein
R 1 and R 2 are same or different linear or branched alkyl, alkoxy or alkanoyloxy of 1-18C, X is H, halogen or CN, t, m and n are 0 or 1 and (ℓ + m + n) is 1 or 2, and has smectic C phase; Component B has the formula
