Abstract:
1. A nematic liquid crystal composition, comprising: one or at least two compounds represented by general formula (I) as a first component: (wherein R R m represents 0, 1, or 2); and one or at least two compounds represented by general formula (II) as a second component: (wherein R B (a) a trans-1,4-cyclohexylene group (in which one CH (b) a 1,4-phenylene group (in which one or at least two CH groups may be replaced by a nitrogen atom), and (c) a 1,4-cyclohexenylene group, a 1,4-bicyclo[2.2.2]octylene group, a piperidine-1,4-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, in which a hydrogen atom of the above group (a), group (b), or group (c) may be replaced by halogen; Y in the case where pluralities of Y p represents 0, 1, or 2), wherein a dielectric anisotropy is negative.
