Abstract
An organic EL device of the invention comprises a hole injecting electrode, an electron injecting electrode and at least one organic layer interleaved between them. The electron injecting electrode is a film of an aluminum lithium alloy formed by a sputtering technique and comprising 0.4 to 14 at % of lithium. The electron injecting electrode further includes on a side of the electron injecting electrode that is not opposite to the organic layer a protective electrode comprising at least one of aluminum, aluminum and a transition metal except titanium, titanium, and titanium nitride.
