Abstract:
[Problem] The present invention aims to provide an electroluminescence device with an improved intermediate layer, for achieving a superior durability and sustainability performance thereof.[Solution] The present invention refers to organic electroluminescence devices having a plurality of light emitting layers 4 between an anode 1 and a cathode 2 with the intermediate layer 3 being interposed between two of the light emitting layers. The intermediate layer 3 comprises one layer 3a selected from a group consisting of a charge transfer complex layer made of a charge transfer complex, a metal layer made of a metal having a work function of 3.7 eV or less, and a metal compound layer made of a compound of the metal; an electrically conductive material-containing light transmissive layer 3b; a charge transport organic material layer 3c formed of a charge transport organic material; and a hole injection material layer 3d formed of a hole injection material, which are superimposed in this order. The charge transport material layer 3c is formed to have a thickness in a range of 0.5 nm to 30 nm.
