Abstract

We have developed a transparent passivation layer using 8-hydroxy-quinolinato lithium (Liq) in transparent organic light-emitting devices (TOLEDs). The Liq passivation layer improves the stability of Ca/Ag double layer which have used as a semitransparent cathode, resulting in substantial increase of the efficiency and lifetime by the enhanced luminance because it protects the oxidation of the cathode surface by thermal annealing in the TOLEDs. The passivation layer makes a variety of thick device and is also applicable to wide and flexible display.
