Beschreibung
Zusammenfassung:	To provide a composition for an organic electroluminescent element, which enables the fabrication of an organic electroluminescent element by a wet film deposition method as to phosphorus optical elements and especially, enables the preparation of an organic electroluminescent element low in drive voltage and high in efficiency even in the case of using a polymer compound as an electronic charge-transporting material for a luminescent layer.SOLUTION: A composition for an organic electroluminescent element comprises: a low-molecular-weight compound formed from a carbazole derivative of a particular structure; a polymer compound having a repeating unit containing a carbazole derivative of a particular structure; and a luminescent material. An organic electroluminescent element 10 comprises a luminescent layer formed by use of the composition for an organic electroluminescent element.SELECTED DRAWING: Figure 1 【課題】燐光素子において湿式成膜法によって有機電界発光素子の作成が可能であり、特に高分子化合物を電荷輸送材として発光層に用いた場合であっても、駆動電圧が低く高効率の有機電界発光素子を作成することができる有機電界発光素子用組成物を提供する。【解決手段】特定構造のカルバゾール誘導体からなる低分子化合物と、特定構造のカルバゾール誘導体を含む繰り返し単位を有する高分子化合物と、発光材とを含む有機電界発光素子用組成物。この有機電界発光素子組成物を用いて形成された発光層を有する有機電界発光素子１０。【選択図】図１
