Flexible OELDs were fabricated by using highly conductive poly(3,4‐ethylenedioxy thiophene): p‐toluene sulfonate(PEDOT: PTS) nano‐films, as electrode layers. These conductive PEDOT: PTS films have a high transparency up to 80%, and possess a very low sheet resistance of 100 Ω square −1 at 160‐nm thickness. We report on the fabrication and characterization of a OELD using a PEDOT: PTS for the electrodes and demonstrate its superior performance relative to that of a similar device using the a‐ITO layer. The device has been demonstrated to exhibit light emission in green, brightness level up to 1800 cd/m 2 at the 25 V.
