A liquid crystal composition includes one or more of compounds represented by general formula (i) below and one or more of compounds represented by general formula (ii) below.
In the formulae, R11a and R21a each independently represent an alkyl group having 1 to 8 carbon atoms where one -CH2- or two or more non-adjacent -CH2- in the alkyl group may each independently be substituted with -CH=CH-, - C=C-, -O-, -CO-, -COO-, or -OCO-; one or more hydrogen atoms in the alkyl group may be substituted with a fluorine atom or a chlorine atom; X11a, X12a, X13a, X14a, and X21a each independently represent a hydrogen atom or a fluorine atom; A21a, A22a, and A23a each independently represent a trans-1, 4-cyclohexylene group or a 1,4-phenylene group whose hydrogen atom may be substituted with a fluorine atom or a chlorine atom.
液晶组合物包括下式(i)所代表的一种或多种化合物和下式(ii)所代表的一种或多种化合物。
式中,R11a 和 R21a 各自独立地代表具有 1 至 8 个碳原子的烷基,其中烷基中的一个-CH2-或两个或多个不相邻的-CH2-可各自独立地被-CH=CH-、-C=C-、-O-、-CO-、-COO-或-OCO-取代;烷基中的一个或多个氢原子可被氟原子或氯原子取代;X11a、X12a、X13a、X14a 和 X21a 各自独立地代表一个氢原子或一个氟原子;A21a、A22a 和 A23a 各自独立地代表一个反式-1,4-环己烯基团或一个 1,4-苯基基团,其氢原子可被一个氟原子或一个氯原子取代。
