A liquid crystalline compound expressed by the general formula (1) ##STR1## (wherein R.sub.1 is an alkyl group having 1 to 12 carbon atoms and one CH.sub.2 group in the alkyl group may be replaced by oxygen atom or --CH.dbd.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.
提供一种通式(1)表示的液晶化合物##STR1##(其中R.sub.1是具有1至12个碳原子的烷基,烷基中的一个CH.sub.2基团可能被氧原子或-CH.dbd.CH-代替;X代表氢原子或氟原子;Y代表氢原子或具有1至5个碳原子的烷氧基;l和m分别独立地表示0或1;n和p分别独立地表示0至10的整数,当p为0时,n为1或更多,当Y为烷氧基时,X为氟原子且p为0)。提供了适用于液晶显示装置的液晶组合物,具有高清晰点和降低粘度的功能,并提供了作为液晶组合物组分有用的新型液晶化合物。
