    摘要： An organic electroluminescence (EL) device including an electron transport layer formed between a pair of electrodes, wherein the electron transport layer contains 50˜99.9 wt % of alcohol-soluble polymer and 0.1˜50 wt % of electron transporting material. In the EL device according to the present invention, the electron transport layer can be formed through a spin-coating without damage to the light-emitting layer. Thus, the manufacture process for the organic EL device is simplified, and the time and cost required for the manufacture are reduced.
