摘要：An organic EL device comprises a film form of cathode prepared by a sputteringtechnique, and formed of an alloy of sodium and/or potassium. This cathode is improvedin terms of its adhesion to the interface between the cathode and an organic layer and

electron injection efficiency, resulting in light emission property improvements. Inaddition, this cathode causes less damage to the organic layer, is effective for preventionof occurrence of dark spots, and suffers from little or no degradation of performance.
