The organic EL device of the present invention fulfills the object of
realizing an organic EL device which exhibits an excellent hole injecting
efficiency and an improved light emitting efficiency and which can be
operated at a low drive voltage and manufactured at a reduced cost. In
order to attain such object, the organic EL device comprises a hole
injecting electrode, a negative electrode, and one or more organic layers
between the electrodes wherein at least one of said organic layers has a
light emitting function. A high resistivity inorganic hole injecting layer
is provided between said hole injecting electrode and the organic layer.
This layer has conduction paths for electron blockage and hole
transportation. An inorganic insulative electron injecting and
transporting layer is provided between the light emitting layer and the
negative electrode. This layer contains at least one oxide selected from
strontium oxide, magnesium oxide, calcium oxide, lithium oxide, rubidium
oxide, potassium oxide, sodium oxide and cesium oxide as its main
component.
