Abstract:
1. A liquid crystal composition containing at least one compound selected from the group of compounds represented by formula (1) as a first component and at least one compound selected from the group of compounds represented by formula (2) as a second component: wherein R 1 , R 2 , R 3 and R 4 are independently hydrogen, hydroxy, alkyl having 1 to 12 carbons, alkoxy having 1 to 12 carbons, alkenyl having 2 to 12 carbons, alkenyl having 2 to 12 carbons in which arbitrary hydrogen is replaced by fluorine, or a polymerizable group, and at least one of R 1 , R 2 , R 3 and R 4 is a polymerizable group; R 5 and R 6 are independently alkyl having 1 to 12 carbons, alkoxy having 1 to 12 carbons, alkenyl having 2 to 12 carbons, or alkenyl having 2 to 12 carbons in which arbitrary hydrogen is replaced by fluorine; ring A and ring C are independently 1,4-cyclohexylene, 1,4-phenylene in which arbitrary hydrogen may be replaced by fluorine or chlorine, or tetrahydropyran-2,5-diyl; ring B is 2,3-difluoro-1,4-phenylene, 2-chloro-3-fluoro-1,4-phenylene, 2,3-difluoro-5-methyl-1,4-phenylene, 3,4,5-trifluoronaphthalene-2,6-diyl or 7,8-difluorochroman-2,6-diyl; Z Z 2 , Z 3 and Z 4 are independently a single bond, oxygen, carbonyloxy, alkylene having 1 to 12 carbons or alkylene having 1 to 12 carbons in which arbitrary —CH 2 — is replaced by —O—; Z 5 and Z 6 are independently a single bond, or ethylene; m is 1, 2 or 3; and n is 0 or 1, and a sum of m and n is 3 or less.
