Abstract
An organic electroluminescent light emitting device comprises a hole injecting electrode, an electron injecting electrode and at least one organic layer between said electrodes. The electron injecting electrode is a film of an AlLi alloy formed by a sputtering technique. The AlLi alloy comprises 0.1 to 20 at % of lithium and contains as a subordinate component at least one of Cu, Mg and Zr in an amount of PA1 Cu: .ltoreq.10 wt % PA1 Mg: .ltoreq.5 wt % PA1 Zr: .ltoreq.0.5 wt % per the total sum of aluminum and lithium.
