Title
(EN) ORGANIC LIGHT EMITTING DEVICE
(FR) DISPOSITIF ÉLECTROLUMINESCENT ORGANIQUE
Abstract
(EN)
The present invention relates to an organic light emitting device comprising a layered structure including a substrate, a bottom electrode and a top electrode, wherein the bottom electrode is closer to the substrate than the top electrode, the region between the bottom electrode and the top electrode defining an electronically active region, wherein the electronically active region comprises a scattering layer having a thickness of less than 50 nm; and an organic light emitting device additionally having at least one light emitting layer in the electronically active region, and this device further comprising a specific chemical compound outside of the electronically active region.
(FR)
La présente invention concerne un dispositif électroluminescent organique comprenant une structure stratifiée comportant un substrat, une électrode inférieure et une électrode supérieure, l'électrode inférieure étant plus proche du substrat que l'électrode supérieure, la zone entre l'électrode inférieure et l'électrode supérieure définissant une zone électroniquement active, la zone électroniquement active comprenant une couche de diffusion présentant une épaisseur inférieure à 50 nm; et un dispositif électroluminescent organique présentant en outre au moins une couche électroluminescente dans la zone électroniquement active, le dispositif comprenant en outre un composé chimique spécial à l'extérieur de la zone électroniquement active.
