Abstract

The invention relates to the field of organic electronic devices (1) with diffusion barriers and to a method to manufacture such organic electronic devices (1) to provide an organic electronic device (1) with excellent performance, which is as stable as possible over time. The organic electronic device (1) with a substrate (2), a first electrode (3) arranged on top of the substrate (2) and a functional layer stack (FLS) arranged on top of the first electrode (3) comprising one or more organic layers (41, 42, 43) and a second electrode (5), wherein the organic electronic device (1) further comprises at least one essentially transparent and electrically conductive graphene layer (6) arranged in contact to at least one of the organic layers (41, 42, 43) acting as a diffusion barrier against diffusion of atoms, ions or molecules into this organic layer (41, 42, 43).
