We are researching air‐stable inverted OLEDs to realize long‐lifetime flexible displays. Although operationally stable red and green devices have been developed, a blue device has not yet been demonstrated. Here, we developed an operationally stable inverted OLED with an expected half lifetime of over 40,000 h at 500 cd/m 2 .
