Abstract
The invention relates to an electrical device comprising an electrical unit () like an organic light emitting diode, a protection element () like a thin film encapsulation, which at least partly covers the electrical unit, for protecting the electrical unit against water and/or oxygen, and a detection layer () arranged between the protection element and the electrical unit or within the protection element, wherein the detection layer comprises organic material and is adapted such that a property of the detection layer is changed, if the detection layer is in contact with a contact gas usable for detecting a permeability of the protection element. This allows easily integrating a fast detection test for detecting a permeability of the protection element into a production process for producing the electrical device, i.e. a time consuming external permeability test may not be required.
