Abstract
(EN)
A plurality of organic layers (120) are positioned between a first electrode (110) and a second electrode (130), and have light emitting layers, respectively. A charge generating layer (200) is positioned between the organic layers (120) that are adjacent to each other. In other words, though the organic layers (120) are laminated to each other, the charge generating layer (200) is provided between the organic layers (120). The charge generating layer (200) has a first layer, a second layer, and a third layer. The first layer contains an electron transport material, and the second layer contains a metal and a hole injection material. The third layer is formed using a hole transport material. Furthermore, the charge generating layer (200) includes an electron injection material on the first layer side from the second layer, said electron injection material improving electron injection characteristics of the first layer.

Selon la présente invention, une pluralité de couches organiques (120) sont positionnées entre une première électrode (110) et une seconde électrode (130), et ont des couches électroluminescentes, respectivement. Une couche de génération de charges (200) est positionnée entre les couches organiques (120) qui sont adjacentes les unes aux autres. En d'autres termes, bien que les couches organiques (120) soient stratifiées les unes sur les autres, la couche de génération de charges (200) est disposée entre les couches organiques (120). La couche de génération de charges (200) a une première couche, une deuxième couche et une troisième couche. La première couche contient une matière de transport d'électrons, et la deuxième couche contient un métal et une matière d'injection de trous. La troisième couche est formée à l'aide d'une matière de transport de trous. En outre, la couche de génération de charges (200) comprend une matière d'injection d'électrons sur le côté première couche depuis la deuxième couche, ladite matière d'injection d'électrons améliorant des caractéristiques d'injection d'électrons de la première couche.

複数の有機層(120)は第1電極(110)と第2電極(130)の間に位置しており、それぞれが発光層を有している。電荷発生層(200)は隣り合う有機層(120)の間に位置している。言い換えると、複数の有機層(120)は互いに積層されているが、これら複数の有機層(120)の間には電荷発生層(200)が設けられている。電荷発生層(200)は、第1層、第2層、及び第3層を有している。第1層は電子輸送性材料を含んでおり、第2層は金属及び正孔注入材料を含んでいる。第3層は、正孔輸送性材料を用いて形成されている。また、電荷発生層(200)は、第2層より第1層側に、第1層の電子注入性を高める電子注入材料を含んでいる。
