We demonstrate a transparent AgO x top anode by formed by O 2 plasma treatment for inverted top‐emitting organic light emitting diodes (ITOLEDs). The turn‐on voltage decreased from 22 to 12 V, and the luminance increased from 175 to 630 cd/m 2 by using this transparent AgO x anode. The AgO x lowered the injection barrier for holes, enhancing the electroluminescent properties of ITOLEDs.
