Organic electroluminescent device

摘要

In an organic electroluminescent device according to the present invention, at least a carrier transporting layer and a luminescent layer which use an organic material are provided between a hole injection electrode and an electron injection electrode, wherein a luminescent portion having a luminescent peak wavelength different from a luminescent peak wavelength in the luminescent layer is partially provided in such a manner that it is laminated on the luminescent layer, or at least a hole transporting layer having luminous characteristics and an electron transporting layer having luminous characteristics which respectively contain organic materials emitting fluorescence in different colors in a visible region are provided between the hole injection electrode and the electron injection electrode, wherein a hole transporting portion having non-luminous characteristics is partially provided between the hole transporting layer having luminous characteristics and the electron transporting layer having luminous characteristics when the hole transporting layer having luminous characteristics emits light, while an electron transporting portion having non-luminous characteristics is partially provided between the electron transporting layer having luminous characteristics and the hole transporting layer having luminous characteristics when the electron transporting layer having luminous characteristics emits light.
