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 (α) having three or more triphenylamine skeletons, the hole-transporting layer contains an arylamine compound (β) 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.
一种有机电致发光器件包括阳极和阴极之间的空穴注入层、空穴传输层、发光层和电子传输层,其中空穴注入层包含具有三个或三个以上三苯胺骨架的芳胺化合物(α),空穴传输层包含具有两个三苯胺骨架的芳胺化合物(β),电子传输层包含具有蒽环骨架和吡啶吲哚环骨架的电子传输化合物。这种有机电致发光器件发光效率高,驱动电压低,具有出色的耐用性和长使用寿命。
