We report recent progresses on organic light emitting devices such as organic light emitting diode (OLED), light‐emitting organic field effect transistor (LE‐OFET) and organic laser diode (OLD). We demonstrate very low driving voltage of OLEDs using a p‐i‐n structure which also provides high current carrier injection over kA/cm 2 . Further we demonstrate novel organic devices such as light emitting FET. We also discuss future prospect of OLD based on our recent materials' development and analysis of operation mechanism.
