The invention provides an organic electroluminescent light emitting device comprising essentially comprising a substrate, a hole injecting electrode formed on at least said substrate, a light emitting layer and an electron injecting electrode containing a constituting material having a work function of up to 4 eV. The electron injecting electrode has a sealing film on a side thereof not opposite to the substrate. This sealing film contains one or two or more of an oxide, a nitride and a carbide of the constituting material for the electron injecting electrode, and so can be relatively easily formed continuously from the electron injecting electrode without any dedicated equipment for sealing films, while maintaining a high sealing effect. The invention also provides a process of producing such an organic electroluminescent light emitting device.
An organic EL device comprising at least a substrate and a hole injecting electrode, a light emitting layer and an electron injecting electrode containing a constituting material having a work function of up to 4 eV formed on said substrate, wherein:
