摘要：
A liquid crystal mixture containing (a) at least one compound of a compound of the formula (1):
in which R is a C₁-C₁₂ alkyl group, etc.; X₁, X₂, X₃, X₄, Y₁, Y₂, Y₃ and Y₄ represent, independently each other, CH, CF or N; A is a hydrogen atom, a 4-R₁-(cycloalkyl) group, etc. in which R₁ is a C₁-C₁₂ alkyl group, etc. and p is 0 or 1; and Z is -C≡C- or a single bond, and (b) at least one compound of the formula (4):
wherein rings C, D, E and F represent, independently each other, 1,4-phenylene, etc. which may be substituted by 1, 2 or 3 fluorine atoms; R₂ is a hydrogen atom, a C₁-C₁₂ alkyl group, etc.; R₃ is a hydrogen atom, a fluorine atom, a fluoromethyl group, etc.; Z₁, Z₂ and Z₃ represent, independently each other, -COO-, -OCO-, -OCH₂-, -CH₂O-, a C₁-C₅ alkylene group, a C₂-C₅ alkenylene group, etc.; J and K
represent, independently each other, a methylene group or -O-; a, b, c, d and e represent, independently each other, 0 or 1.
