摘要:
Disclosed is a liquid crystal composition suitable for producing a liquid crystal electrooptical element which can be driven at a low voltage in a wide temperature range and has high display quality. Also disclosed is a liquid crystal electrooptical element produced by using the liquid crystal composition. Further disclosed is a liquid crystal compound represented by the formula [R1-(A1)a-Z1-(A2)b-Z2-(A7)e-Z5-A3—CF═CFCF2O-A4-Z3-(A5)c-Z4-(A6)d-R2]. In the formula, R1 and R2 independently represent a hydrogen atom, a halogen atom, —CN, —NCS, —SF5, or an alkyl group containing 1 to 18 carbon atoms; A1, A2, A3, A4, A5, A6 and A7 independently represent trans-1,4-cyclohexylene group, 1,4-cyclohexenylene group, 1,3-cyclobutylene group, 1,2-cyclopropylene group, naphthalene-2,6-diyl group, 1,2,3,4-tetrahydronaphthalene-2,6-diyl group, decahydronaphthalene-2,6-diyl group, or 1,4-phenylene group; Z1, Z2, Z3, Z4, and Z5 independently represent a single bond, an alkylene group containing 1 to 4 carbon atoms; and a, b, c, d, and e independently represent 0 or 1 with the proviso that 0≦a+b+c+d+e≦3.
