LIQUID CRYSTAL COMPOSITION, LIQUID CRYSTAL DISPLAY ELEMENT, AND LIQUID CRYSTAL DISPLAY

摘要

There is provided a liquid crystal composition containing at least any one of compounds represented by General Formula (i) and at least any one of compounds represented by General Formula (ii). In the formulae, R i1 represents an alkyl group having 1 to 8 carbon atoms; and A i1 represents a 1,4-cyclohexylene group (of which one -CH 2 - or at least two -CH 2 - not adjoining each other are optionally substituted with -O-), a 1,4-phenylene group (of which at least one hydrogen atom is optionally substituted with a fluorine atom), or a single bond;
R ii1 represents an alkyl group having 1 to 8 carbon atoms;
and one -CH 2 - or at least two -CH 2 - not adjoining each other in the alkyl group are each independently optionally substituted with -CH=CH-, -C=C-, -O-, -CO-, -COO-, or -OCO-;
R ii2 represents a fluorine atom, a chlorine atom, a cyano group, or an alkyl group having 1 to 8 carbon atoms; one-CH 2 - or at least two -CH 2 - not adjoining each other in the alkyl group are each independently optionally substituted with -CH=CH-, -C=C-, -O-, -CO-, -COO-, or -OCO-; and one or two or more hydrogen atoms of the alkyl group are each independently optionally substituted with a fluorine atom;
A ii1 and A ii2 each independently represent a 1,4-cyclohexylene group (of which one -CH 2 - or at least two -CH 2 - not adjoining each other are optionally substituted with -O-) or a 1,4-phenylene group (of which at least one hydrogen atom is optionally substituted with a fluorine atom);
Z ii1 and Z ii2 each independently represent a single bond, - CH 2 CH 2 -, -(CH 2 ) 4 -, -CH 2 -, -CH 2 O-, -OCF 2 -, -CF 2 O-, -COO-, -OCO-, or -C=C-;
m ii1 and m ii2 each independently represent 0, 1, 2, or 3; and m ii1 + m ii2 is equal to 1, 2, 3, or 4;
in the case where A ii1 and Z ii1 are multiple, the A ii1 moieties and the Z ii1 moieties are the same as or different from each other, respectively; and
in the case where A ii2 and Z ii2 are multiple, the A ii2 moieties and the Z ii2 moieties are the same as or different from each other, respectively.
