    摘要： Liquid crystalline compounds having a comparatively high voltage holding ratio, high &Dgr;n and high &Dgr;&egr;, and excellent miscibility with known liquid crystalline compounds at low temperatures. The novel compounds have the formula (1) wherein R represents hydrogen atom or an alkyl group having 1 to 20 carbon atoms; n1 and n2 are independently 0, 1, or 2 provided that the sum of n1 and n2 is 1 or 2; ring A and ring B independently represent 1,4-phenylene, fluorine substituted 1,4-phenylene expressed by the formula (a) in the specification or 1,4-cyclohexylene provided that at least one of ring A and ring B is fluorine substituted 1,4-phenylene expressed by the formula (a); Za, Zb, and Zc independently represent single bond, —CH2CH2—, —COO—, —CF2O—, or —CH2CH2CH2CH2—; Q1, Q2, Q3, Q4, Q5, Q6, and Q7 independently represent hydrogen atom, a halogen atom, or methyl group provided that when at least one of Za, Zb, and Zc is —CH2CH2—, then Q2 is fluorine atom, and that when Za, Zb, and Zc are all single bonds, then Q1, Q2, Q3, Q4, Q5, Q6, and Q7 independently represent hydrogen atom or fluorine atom; Y represents hydrogen atom, a halogen atom, or a halogenated alkyl group having 1 to 5 carbon atoms; and each atom constituting this compound may be replaced by its isotope.
