Abstract
An organic electroluminescent device, including a substrate, a first electrode layer formed on the substrate, and a second electrode layer formed on the first electrode layer. An organic layer, having a light-emitting layer, is interposed between the first electrode layer and the second electrode layer, and a transparent layer is formed on the second electrode layer. Damage to the organic layer may be prevented while maintaining a transmittance of the second electrode layer.
