Poly(phenylenevinylene)‐based organic light‐emitting diodes (OLEDs) are fabricated using air‐stable metal oxides as electrodes, producing very efficient and bright electroluminescent devices. Efficiencies of 8 cd A −1 and luminances above 20000 cd m −2 are obtained, comparable to the values reported for classic OLED structures using reactive metals as cathodes.
