Zusammenfassung:	To provide an organic EL element stable in the atmosphere with less dependency on the film thickness of a drive voltage by developing a carrier injection material used for an electron injection layer or a hole injection layer.SOLUTION: There is provided an organic EL device including an ionic compound carrier injection material represented by the following formula (1). (In the formula (1), Rand Reach independently represent an alkyl group, Rand Reach independently represent an alkyl group containing a fluorine atom, and n is an integer of 1 or more.)SELECTED DRAWING: None 【課題】本発明は、電子注入層やホール注入層に用いるキャリア注入材料を開発することにより、駆動電圧の膜厚依存性が少なく、大気中で安定な有機ＥＬ素子を提供することを課題とする。【解決手段】下記式（１）で表されるイオン性化合物キャリア注入材料を含むことを特徴とする有機ＥＬ素子。（式（１）中、Ｒ1及びＲ２はそれぞれ独立にアルキル基を表し、Ｒ3及びＲ4はそれぞれ独立にフッ素原子を含むアルキル基を表し、ｎは１以上の整数を表す。）【選択図】なし
