<p>With the aim of making possible efficient production at low cost of a laminate having a multitude of units, there is provided an organic electroluminescent element into which are introduced intermediate layers (charge generating layers) of novel structure composed of organic material only, without the use of the metal aluminum (Al), which has a vapor deposition temperature in excess of 1,200°C. The present invention pertains to an organic electroluminescent element of stack type (multi-photon type), characterized by having an anode, a cathode, a plurality of light-emitting units situated between the anode and the cathode, and including a light-emitting layer, and intermediate layers situated between the plurality of light-emitting units, the intermediate layers being constituted by mixed layers of a fullerene compound, and an electron-donating organic material having the function of donating electrons to the fullerene compound.</p> |
