Disclosed is a composition containing one or more aromatic ether compounds, one or more compounds having a boiling point of not less than 200°C, and one or more polymers which are charge-transporting or luminescent in a solid state. This composition is characterized in that the compounds having a boiling point of not less than 200°C are selected from the group consisting of aliphatic compounds which may have a heteroatom, alicyclic compounds which may have a heteroatom, aromatic compounds having two or less substituents and a heterocyclic compounds having two or less substituents. |
