PCT No. PCT/JP94/01914 Sec. 371 Date Jul. 24, 1996 Sec. 102(e) Date Jul. 24, 1996 PCT Filed Nov. 11, 1994 PCT Pub. No. WO95/20021 PCT Pub. Date Jul. 27, 1995A liquid crystalline compound expressed by the general formula (1) <IMAGE> (1) (wherein R1 is an alkyl group having 1 to 12 carbon atoms and one CH2 group in the alkyl group may be replaced by oxygen atom or -CH=CH-; X represents hydrogen atom or fluorine atom; Y represents hydrogen atom or alkoxy group having 1 to 5 carbon atoms; l and m independently represent 0 or 1, respectively; and n and p independently represent an integer of 0 to 10, respectively, and when p is 0, n is 1 or more, and when Y is an alkoxy group, X is a fluorine atom and p is 0.) Liquid crystal compositions which are suitable for use in liquid crystal display devices, have a high clearing point, and have a function of decreasing viscosity, and novel liquid crystalline compounds useful as a component of the liquid crystal compositions are provided. |
