A liquid crystal composition comprising one or more compounds represented by the following general formula (i) and one or two or more compounds represented by the following general formula (ii). ( Wherein R i1 and R ii1 each independently represent an alkyl group having 1 to 8 carbon atoms, and one or more non-adjacent two -CH 2 - groups in the alkyl group are independently -CH = CH-, -C≡C-, -O-, -CO-, -COO- or -OCO-, and one or two or more hydrogen atoms of the alkyl group may be independently substituted with a fluorine atom or a chlorine atom M i1 represents 0, 1 or 2, A i1 represents a 1,4-phenylene group in which a hydrogen atom may be substituted by a fluorine atom or a chlorine atom, and when m i1 is 2, A i1 are be the same or different, X i1 is a hydrogen atom, a fluorine atom or a chlorine atom, m ii1 represents 0 or 1, X ii1, X ii2, X ii3 and X ii4 is independently a hydrogen atom, a fluorine atom, respectively Or a chlorine atom, and X ii5 represents a hydrogen atom, a fluorine atom, a chlorine atom, a cyano group, - CF 3 or -OCF 3 ) |
