Abstract (en)
[origin: WO2007130047A1] An OLED includes an anode (120) , a light emitting layer (150) disposed over the anode (120), and a first electron injecting layer disposed over the light- emitting layer, wherein the first electron- injecting layer (271) includes at least one organic host material having a reduction potential less than -1.0 V vs. a Saturated Calomel Electrode and at least one dopant material capable of reducing the organic host material. The OLED also includes a second electron-injecting layer (272) disposed in contact with the first electron- injecting layer (271) , wherein the second electron- injecting layer (272) includes at least one organic material having a reduction potential greater than -1.0 V vs . a Saturated Calomel Electrode, and a cathode (180) disposed over the second electron- injecting layer (272) .
