发明名称 Organic electroluminescent device.
摘要 <p>There is disclosed an organic electroluminescent device, comprising a multilayered structure of an organic film for electron injection, and an organic film for hole injection, at least one of which consists of a plurality of layers, and an organic film serving as a light-emitting layer interposed therebetween, a first electrode for electron injection formed on the side of the organic film for electron injection of the multilayered structure, and a second electrode for hole injection formed on the side of the organic film for hole injection of the multilayered structure, wherein a barrier height against electron injection at each interface between layers present from the first electrode to the organic film serving as the light-emitting layer is not more than 0.6 eV, and a barrier height against hole injection at each interface between layers present from the second electrode to the organic film serving as the light-emitting layer is not more than 0.6 eV. &lt;IMAGE&gt;</p>
