There is provided a composition containing a compound represented by General Formula (i) and a compound represented by General Formula (ii) (where Ri1, Rii1, and Rii2 each independently represent an alkyl group having 1 to 8 carbon atoms; in the alkyl group, one —CH2— group or two or more —CH2— groups not adjoining each other are each independently optionally substituted with —CH═CH—, —C≡C—, —O—, —CO—, —COO—, or —OCO—; mi1 represents 2; Ai1 represents a 1,4-cyclohexylene group or a 1,4-phenylene group of which a hydrogen atom is optionally substituted with a fluorine atom or a chlorine atom; multiple Ai1's may be the same as or different from each other; Zi1 represents a single bond, —CH═CH—, —C≡C—, —CH2CH2—, —COO—, or —OCO—; multiple Zi1's may be the same as or different from each other; and Xi1 and Xii1 to Xii4 each independently represent a hydrogen atom or a fluorine atom).
