Abstract Organic light emitting devices (OLEDs) have been fabricated on various flexible substrates using conducting polymers as anodes. In this paper we report on the performance of OLEDs using films of highly conductive Poly(3,4‐ethylenedioxythiophene) poly(styrenesulfonate) (PEDOT:PSS) anodes without an indium tin oxide under‐layer. The conducting polymer anodes are formed using a simple patterning method.
