More Information
Summary:In a light emitting element according to the present invention, an intermediate layer including at least one of ZnS, a metal oxide, and a metal fluoride is provided between a first electrode and a first charge transport layer and/or between a second electrode and a second charge transport layer. Selon la présente invention, dans un élément électroluminescent, une couche intermédiaire comprenant au moins un élément parmi un ZnS, un oxyde métallique et un fluorure métallique, est agencée entre une première électrode et une première couche de transport de charge et/ou entre une seconde électrode et une seconde couche de transport de charge. 発光素子では、第１電極と第１電荷輸送層との間、及び第２電極と第２電荷輸送層との間の少なくとも一方の間において、ＺｎＳと、金属酸化物及び金属フッ化物の少なくとも一方を含んだ中間層が設けられている。
