Air‐stable OLEDs are necessary for expanding the availability of OLEDs. We examined the configuration of the electron injection layer (EIL) suitable for air‐stable OLEDs. An OLED with high operational stability was demonstrated by employing a newly developed EIL that requires no chemical n‐doping for electron injection from the bottom cathode.
