摘要：
The present invention provides an organic light-emitting element with improved chemical stability at the interface between the light-emitting layer and the electron transport layer, which maintains excellent, stable luminous efficiency for a long period. For this purpose, one aspect of the present invention is an organic EL element having a substrate, and a hole injection layer, a buffer layer, a light-emitting layer, a regulation layer, an electron transport layer and a cathode which are sequentially layered on one side of the substrate. The regulation layer is made of NaF, which is not chemically reactive with the light-emitting layer or the electron transport layer, and the electron transport layer is made of a CT complex using a host material and an n-type dopant, which are both organic materials.
