摘要： Organic electroluminescent elements capable of operating at a low driving voltage, leading to saving of electric power and operating cost for a driving circuit. In an organic electroluminescent element in which a hole transport layer and a luminous layer are formed between a hole injecting electrode layer and an electron injecting electrode layer which are oppositely arranged in a pair and in which the hole transport layer is overlaid on the hole injecting electrode layer, the hole transport layer is doped with a hole injection material at least at a region near the interface between the hole transport layer and a hole injecting electrode. The hole injection material has an ionization potential which is lower than that of the material of the hole transport layer and higher than that of the material of the hole injecting electrode layer.
