Abstract

An organic electroluminescent device is provided, including a substrate and a composite anode structure disposed thereon, wherein the composite anode structure includes a lower metal oxide layer, a metallic silver layer and an upper metal oxide layer, wherein metallic silver at portions of a surface of the metallic silver layer which are not covered by the upper metal oxide due to defects of the upper metal oxide layer includes silver oxide. During the preparation of the organic electroluminescent device, the substrate is stored in the atmosphere for a long time while maintaining the performance of the substrate substantially unchanged, thereby improving the performance and the yield of the device.
