Abstract:
1. A liquid crystal composition containing a polymerizable compound, comprising: as a first component as the polymerizable compound, at least one compound selected from compounds represented by general formula (I) wherein R S Z wherein R X m represents 0 or 1 and n represents 1, 2, or 3, L L M as a second component as a non-polymerizable liquid crystal material, at least one compound represented by general formula (II) wherein R o represents 0, 1, or 2, M (a) a trans-1,4-cyclohexylene group (one methylene group or two or more methylene groups that are not adjacent to each other in this group may be substituted with —O— or —S—), (b) a 1,4-phenylene group wherein one —CH═ or two or more —CH═ that are not adjacent to each other in this 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(2.2.2)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, and when a plurality of M L as a third component having positive or negative Δε, at least one compound selected from the group consisting of compounds represented by general formulae (IIIa), (IIIb), and (IIIc) or the group consisting of compounds represented by general formulae (IVa), (IVb), and (IVc) wherein R p, q, r, s, and t each independently represent 0, 1, or 2, where q +r and s +t are each 2 or less, M (d) a trans-1,4-cyclohexylene group wherein one methylene group or two or more methylene groups that are not adjacent to each other in this group may be substituted with —O—or —S—, (e) a 1,4-phenylene group wherein one —CH═ or two or more —CH═ that are not adjacent to each other in this 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, and when a plurality of M L X Y wherein R 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, M (d) a trans-1,4-cyclohexylene group wherein one methylene group or two or more methylene groups that are not adjacent to each other in this group may be substituted with —O— or —S—, (e) a 1,4-phenylene group wherein one —CH═ or two or more —CH═ that are not adjacent to each other in this group may be substituted with a nitrogen atom, 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), 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, and when a plurality of M L X G represents a methylene group or —O—.
