Abstract:
1. A liquid crystal composition comprising: as a first component, at least one compound selected from polymerizable compounds represented by general formula (I): wherein R S Z wherein R X L L M m represents 0 or 1 and n represents 1, 2, or wherein when n represents 2 or 3, two or three M wherein R M (a) a trans-1,4-cyclohexylene group where a methylene group or two or more methylene groups that are not adjacent to each other in the cyclohexylene group may be substituted with —O— or —S—, (b) a 1,4-phenylene group where one —CH═ or two or more —CH═ that are not adjacent to each other in the phenylene group may be substituted with a nitrogen atom, a 3-fluoro-1,4-phenylene group, and a 3,5-difluoro-1,4-phenylene group, and (c) a 1,4-cyclohexenylene group, a 1,4-bicyclo(2.22)octylene group, a piperidine-2,5-diyl group, a naphthalene-2,6-diyl group, a decahydronaphthalene-2,6-diyl group, and a 1,2,3,4-tetrahydronaphthalene-2,6-diyl group, o represents 0, 1, or 2, L wherein R M (d) trans-1,4-cyclohexylene group where a methylene group or two or more methylene groups that are not adjacent to each other in the cyclohexylene group may be substituted with —O— or —S—, (e) a 1,4-phenylene group where one —CH═ or two or more —CH═ that are not adjacent to each other in the phenylene group may be substituted with a nitrogen atom, a 3-fluoro-1,4-phenylene group, and a 3,5-difluoro-1,4-phenylene group, and (f) a 1,4-cyclohexenylene group, a 1,4-bicyclo(2.2.2)octylene group, a piperidine-2,5-diyl group, a naphthalene-2,6-diyl group, a 1,2,3,4-tetrahydronaphthalene-2,6-diyl group, and a decahydronaphthalene-2,6-diyl group, a hydrogen atom in the group (d), groups (e), or groups (f) may be substituted with a cyano group, a fluorine atom, a trifluoromethyl group, a trifluoromethoxy group, or a chlorine atom, L X Y at least one of X at least one of X at least one of X p, q, r, s, and t each independently represent 0, 1, or 2, where q+r and s+t are each 2 or less, wherein R M (d) a trans-1,4-cyclohexylene group where a methylene group or two or more methylene groups that are not adjacent to each other in the cyclohexylene group may be substituted with —O— or —S—, (e) a 1,4-phenylene group where one —CH═ or two or more —CH═ that are not adjacent to each other in this the phenylene group may be substituted with a nitrogen atom, a 3-fluoro-1,4-phenylene group, and a 3,5-difluoro-1,4-phenylene group, and (f) a 1,4-cyclohexenylene group, a 1,4-bicyclo(2.2.2)octylene group, a piperidine-2,5-diyl group, a napthalene-2,6-diyl group, a 1,2,3,4-tetrahydronaphthatene-2,6-diyl group, and a decahydronaphthalene-2,6-diyl group, a hydrogen atom in the group (d), group (e), or groups (f) may be substituted with a cyano group, a fluorine atom, a trifluoromethyl group, a trifluoromethoxy group, or a chlorine atom, L X G represents a methylene group or —O—, and u, v, w, x, y, and z each independently represent 0, 1, or 2, where u+v, w+x, and y+z are each 2 or less.
