摘要：An organic electroluminescent device includes an anode; a hole-transportinglayer disposed over the anode; a light-emitting layer disposed over the hole-transportinglayer for producing blue light in response to hole-electron recombination, wherein thelight emitting layer includes at least one host material and at least one dopant material;a non-hole-blocking buffer layer formed in contact with the light-emitting layer, whereinthe non-hole-blocking buffer layer has substantially the same ionization potential andthe same electron affinity as those of one of the host materials in the light-emittinglayer; an electron-transporting layer disposed over the non-hole-blocking buffer layer;and a cathode disposed over the electron-transporting layer.
