Abstract

L'invention porte sur un élément électroluminescent organique, qui possède un rendement d'émission de lumière blanche amélioré, et peut en outre même être fabriqué par un procédé simple tel qu'un procédé humide. L'élément électroluminescent organique comprend, sur un substrat, au moins une anode, une cathode, une couche électroluminescente intercalée entre l'anode et la cathode, et une couche de transport de trous, et la couleur de la lumière émise par l'élément est blanche. La couche électroluminescente contient au moins un dopant phosphorescent de deux types ou plus ayant des valeurs ?max différentes, et une couche intermédiaire est agencée entre la couche électroluminescente et la couche de transport de trous.
