摘要：
In an electroluminescent device which comprises a layer of a semiconductive conjugated polymer between positive and negative charge carrier injecting electrodes, a barrier layer is arranged between the layer of semiconductive conjugated polymer and the charge carrier injecting layer for negative charge carriers. The barrier layer protects the layer of semiconductive conjugated polymer from for example mobile ions released by the reactive charge carrier injecting layer. The barrier layer can in some circumstances also itself be light-emissive.
