Extracting light from the waveguide mode in organic light‐emitting diodes (OLED) is most challenging as such optical mode is intrinsically formed due to materials and layered structure used in the device. Here, we show that a metal‐only transparent conductor based an ultrathin Cu‐Ag film can be used to eliminate the guided mode, thus enhancing light extraction efficiency in OLED.
