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, R i1 and R ii1 independently represent an alkyl group having 1 to 8 carbon atoms, and one -CH 2 - group or two or more -CH 2 - 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; m i1 represents 0, 1 or 2; A i1 represents 1,4-phenylene group in which a hydrogen atom may be substituted by a fluorine atom or a chlorine atom, and when m i1 represents 2, A i1 may be the same or different; X i1 independently represents 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 independently represent a hydrogen atom, a fluorine atom 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 .)
