The organic electroluminescent device using the same and an aromatic amine compound, and a display device using an organic electroluminescent device

摘要

PROBLEM TO BE SOLVED: To provide an aromatic amine compound exhibiting a high fluorescence quantum yield and red luminescence and having excellent stability, an organic electroluminescent element using the same and a display element using the same.;SOLUTION: The organic electroluminescent element includes a transparent positive electrode 2, a luminescent layer 5 and a negative electrode 3 that are laminated on a substrate 1 and a protective film 4. A luminescence 30 includes luminescence reflected by the negative electrode, transmits the positive electrode and is observed from the transparent substrate side. The luminescent layer contains an aromatic amine compound in which -X¹, -X² and -(Ar¹-Ar²-Y_n) are bonded to nitrogen (wherein X¹ and X² are each the same or different and selected from alkyl, aryl, allyl, alkoxy and aryloxy; Ar¹ and Ar² are each arylene; and at least one of Y (n≥1) is a group selected from trifluoromethyl, cyano and halogen and the residue is a group selected from hydro, alkyl, aryl, allyl, alkoxy and aryloxy).;COPYRIGHT: (C)2010,JPO&INPIT
