Document Type and Number:
Japanese Patent JPH0768518
Kind Code:
B2
Abstract:
A ferroelectric liquid crystal composition, which may be used in a light switching element, comprises a ferrorelectric liquid crystal composition comprising three liquid crystal components A, B and C, and containing from 10 to 70% by weight, based on the total of components A, B and C, of component A which comprises one or more compounds of the formulae: (in which R<1> and R<2> are the same or are different and each is a C1-C18 group), and (in which R<3> and R<4> are the same or are different, and each is a C1-C18 alkyl or C1-C18 alkoxy group); from 10 to 50% by weight, based on the total of components A, B and C, of component B which comprises one or more compounds of the formula: (in which R<5> is a C1-C18 alkyl group, n is 0 or an integer from 1 to 10; and * indicates an asymmetric carbon atom); and from 10 to 40% by weight, based on the total of components A, B and C, of component C which comprises one or more compounds of the formuale: (in which R<6> is a C1-C18 alkyl or C1-C18 alkoxy group and * represents an assymmetric carbon atom), and (in which R<7> is a C1-C18 alkyl group or C1-C18 alkoxy group and * indicates an asymmetric carbon atom).
