A liquid crystal composition including one or two or more compounds selected from the group consisting of compounds represented by general formula (i) shown below, and one or two or more compounds selected from the group consisting of compounds represented by general formula (ii) shown below.
(In formulae, Ri1 and Rii1 independently represent an alkyl group having 1 to 8 carbon atoms, and one -CH2- group or two or more -CH2- groups which are not adjacent to each other in the alkyl group may be independently substituted by -CH=CH-, -C≡C-, -O-, -CO-, -COO- or -OCO, and one or two or more hydrogen atoms in the alkyl group independently may be substituted by a fluorine atom or a chlorine atom; mi1 represents 0, 1 or 2; Ai1 represents 1,4-phenylene group in which a hydrogen atom may be substituted by a fluorine atom or a chlorine atom, and when mi1 represents 2, Ai1 may be the same or different; Xi1 independently represents a hydrogen atom, a fluorine atom or a chlorine atom; mii1 represents 0 or 1; Xii1, Xii2, Xii3 and Xii4 independently represent a hydrogen atom, a fluorine atom or a chlorine atom; and Xii5 represents a hydrogen atom, a fluorine atom, a chlorine atom, a cyano group, -CF3 or -OCF3.)
一种液晶组合物,包括一种或两种或两种以上选自由下图通式(i)所代表的化合物组成的化合物组和一种或两种或两种以上选自由下图通式(ii)所代表的化合物组成的化合物组。
(式中,Ri1 和 Rii1 独立地代表具有 1 至 8 个碳原子的烷基,烷基中的一个-CH2-基团或两个或多个互不相邻的-CH2-基团可独立地被-CH=CH-、-C≡C-、-O-、-CO-、-COO-或-OCO取代,烷基中的一个或两个或多个氢原子可独立地被氟原子或氯原子取代;mi1 代表 0、1 或 2;Ai1 代表 1,4-亚苯基,其中一个氢原子可被氟原子或氯原子取代,当 mi1 代表 2 时,Ai1 可以相同或不同;Xi1 独立地代表一个氢原子、一个氟原子或一个氯原子;mii1代表0或1;Xii1、Xii2、Xii3和Xii4独立地代表氢原子、氟原子或氯原子;Xii5代表氢原子、氟原子、氯原子、氰基、-CF3或-OCF3。)
