PROBLEM TO BE SOLVED: To provide an organic electroluminescent element capable of obtaining sufficient luminance with a low voltage, which has stable electrical properties and excels in durability. SOLUTION: The organic electroluminescent element of this invention is composed of organic compound layers inserted between a pair of electrodes, at least one of which is transparent or translucent. At least one layer of the foregoing organic compound layers contains a charge transport type polyester that has a specific diphenylamine dielectric structure. In addition, at least one layer of the foregoing organic compound layers contains a polymer ofπconjugated polymer luminescence. That is the main feature of this organic electroluminescent element.
