要約
(EN) The present invention provides an organic electroluminescent element which has excellent luminous efficiency and excellent luminance. The present invention relates to an organic electroluminescent element which has a structure wherein a plurality of layers are laminated between a positive electrode and a negative electrode that is formed on a substrate, and which comprises a metal oxide layer between the positive electrode and the negative electrode, while having a layer that is adjacent to the metal oxide layer on the positive electrode side, said layer being formed of a nitrogen-containing film and having an average thickness of 0.1 nm or more but less than 3 nm.
(ZH) 本发明提供发光效率和亮度优异的有机电致发光元件。本发明涉及一种有机电致发光元件,其具有在阳极与形成于基板上的阴极之间层积有两个以上的层的结构,该有机电致发光元件在阳极与阴极之间具有金属氧化物层,与该金属氧化物层相邻地在阳极侧具有由含氮膜构成的平均厚度为0.1nm以上且小于3nm的层。
