We developed an 8‐in. VGA flexible OLED display by integrating IGZO‐TFTs and novel highly efficient phosphorescent OLEDs. The emitting layers in red OLEDs using a beryllium complex as a host material and a platinum complex as a guest material exhibited low driving voltage, high luminous efficiency, and high stability because of efficient energy transfer from the host to the guest. Furthermore, IGZO‐TFT backplane was fabricated on the plastic film at low temperature. Stable moving images could be observed on the display when it was bent.
