| titleOfInvention | Ferroelectric Liquid Crystal Composition |
| abstract | Component A, at least one compound selected from compounds of Formula (A) having a Smectic C phase, when dissolved in a Smectic C liquid crystal, an optical formula of Formula (B) in which spontaneous polarization on the chiral smectic C phase is the same. Component B, which is at least one compound selected from the active compounds, and Component C, which is at least one optically active compound of formula (C) that, when dissolved in a Smectic C liquid crystal, causes spontaneous polarization on the chiral smectic C to the same extent as the compound of component B There is provided a ferroelectric Smectic C liquid crystal composition, each having a specified ratio and including a room temperature, exhibiting an SC * phase in a high temperature range and having fast response characteristics, and a photo-switching device using the composition.n n n n n n n n n n n n n In the above formulan n n n n n n n Indicatesn n n n n n n n n n n n n n n n n n n n n n n R 1 and R 2 are the same or different straight or branched chain alkyl groups, alkoxy groups or alkanoyloxy groups having 1 to 18 carbon atoms, R 3 is a straight or branched chain alkyl group or alkoxy group having 1 to 18 carbon atoms, R 4 Is an alkyl group having 2 to 18 carbon atoms or a straight or branched alkoxy group having 1 to 18 carbon atoms, R 5 and R 6 are each the same or different straight or branched chain alkyl group or alkoxy group having 1 to 18 carbon atoms, X, Y and Z is a hydrogen atom, a halogen atom or a cyano group, respectively, l, m and n are integers of 0 or 1, respectively, where the sum of l, m and n is 1 or 2, and k is an integer of 0 or 1 And * represents an asymmetric carbon atom. |
