| 摘要 |
An organic EL device has a structure that includes a hole injecting electrode, hole injecting layer, hole transporting layer, light emitting layer, electron restricting layer, electron transporting layer, and electron injecting electrode, in sequence, on a substrate. For the electron restricting layer, a material having an electron mobility lower than that of the electron transporting layer or a material having a low LUMO (lowest unoccupied molecular orbital) energy level is used.
