We succeeded in developing a single‐unit hybrid organic light‐emitting diode (OLED) device with efficient light emission from both a phosphorescent layer and a fluorescent layer. The single‐unit hybrid OLED achieved power efficiency higher than that of a two‐unit hybrid tandem OLED with a phosphorescent and fluorescent layers.
