Disclosed are(a) liquid crystalline compounds which are essential as component of the liquid crystal compositions, are excellent in miscibility with other liquid crystal compositions, particularly in the miscibility at low temperatures, and expressed by the general formula (1)wherein R0 and R1 independently represent an alkyl group having 1 to 10 carbon atoms; ring A0, ring A1, ring A2, and ring A3 represent 1,4-cyclohexylene group, 1,3-dioxane-2,5-diyl group, 1,4-phenylene group in which one or more hydrogen atoms on the ring may be represented by a halogen atom or R2O group, pyridine-2,5-diyl group, or pyrimidine-2,5-diyl group; Z0, Z1, Z2, and Z3 represent -CH2CH2-, -CH=CH-, -C=C-, -CH2O-, -OCH2-, -CF2O-, -OCF2-, -COO-, -OCO-, -(CH2)4-, or single bond; Q1 and Q2 represent hydrogen atom or a halogen atom; Q3 represents hydrogen atom, a halogen atom, or R2O group; R2 represents an alkyl group having 1 to 10 carbon atoms; Y represents a halogen atom, cyano group, or an alkyl group having 1 to 10 carbon atoms; l, m, n and o are 0, 1, or 2 with the proviso that 1<=l+m+n+o<=3; and the atom which constitutes this compound may be replaced by its isotope; and(b) liquid crystal display devices fabricated by using the liquid crystal composition. |
