Zusammenfassung:	To provide a composition which is useful for production of a light emitting device excellent in luminance life.A composition comprising a primary fluorinated alcohol represented by the formula (1), a secondary fluorinated alcohol represented by the formula (1') and an electron injectable compound or an electron transportable compound, whereinthe content of the secondary fluorinated alcohol is 0.01% by mass to 0.75% by mass with respect to the total content of the primary fluorinated alcohol and the secondary fluorinated alcohol: CnH2n-m+1FmOH (1) Cn'H2n'-m'+1Fm'OH (1')[In the formula (1),n represents an integer of 1 to 10, and m is an integer satisfying 1 ≤ m ≤ 2n+1.In the formula (1'),n' represents an integer of 3 to 10, and m' is an integer satisfying 1 ≤ m' ≤ 2n'+1.].
