摘要：
A liquid crystal composition comprising (1) at least one compound selected from those expressed by the formula (I) and (2) at least one compound selected from those expressed by the formulas (II), (III), (IV) and (V):
wherein R₁ to R₅ are C₁₋₁₀ alkyl; R₆ and R₇ are C₁₋₁₀ alkyl or alkenyl; X is H or F; X₁ and X₂ are F, -CF₃, -OCF₃, -CHF₂ or -OCHF₂; Y₁ and Y₂ are H or F; Z₁, Z₂ and Z₄ are -COO-, -CH₂CH₂-or a single bond; Z₃, Z₅ and Z₆ are -COO-, -CH₂CH₂-, -C≡C- or a aingle bond; and A is
which composition is provided with characteristics of high specific resistance, low viscosity while keeping small current consumption, a suitable clearing point and threshold voltage.
