| description | The purpose of the present invention is to provide a flexible organic electroluminescent element having higher characteristics and lower cost. The purpose of the present invention is, in particular, to solve at least one of the following problems: an increase in driving life and a problem of driving at a low voltage; the present invention also addresses the problem of providing an organic electroluminescent element which can emit light satisfactorily and has excellent atmospheric stability. The present invention relates to an organic electroluminescent element having at least one pair of electrodes and an organic layer between the pair of electrodes, the organic electroluminescent element being characterized in that: a metal electron injection layer and an organic electron injection layer each contain a metal species and an organic material that can be coordinated and bonded; the metal electron injection layer and the organic electron injection layer are arranged adjacent to the cathode in this order.
