Beschreibung
Zusammenfassung:An organic electroluminescent device comprises, between an anode and a cathode, a hole injection layer, a hole-transporting layer, a luminous layer and an electron-transporting layer, wherein the hole injection layer contains an arylamine compound (±) having three or more triphenylamine skeletons, the hole-transporting layer contains an arylamine compound (²) having two triphenylamine skeletons, and the electron-transporting layer contains an electron-transporting compound having an anthracene ring skeleton and a pyridoindole ring skeleton. The organic EL device emits light highly efficiently, drives on a low voltage, and features excellent durability and long life.
