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/cm2. 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.
