Abstract
The invention relates to an organic optoelectronic device which is protected from ambient air by a sealed encapsulation structure of the type including at least one thin layer. The device includes a substrate; at least one light-emitting unit deposited on the substrate, incorporating internal electrodes and external electrodes defining an active zone and, between the electrodes, a stack of organic films; and a sealed encapsulation structure having one or more thin layers including at least one inorganic layer placed on top of the light-emitting unit and encasing same laterally. The device also includes a pre-encapsulation structure located between the external electrode and the encapsulation structure and which includes a buffer layer covering the external electrode and contains a heterocyclic organometallic complex having a glass transition temperature above 80° C., and a barrier layer covering the buffer layer and contains a silicon oxide SiOx, wherein x is 0<x<2.
