A method for producing an organic electronic device and organic electronic device

particularly to a method for producing an organic electronic device comprising the steps of: A) producing at least a functional layer stack (10) with the partial steps: A1) providing a flexible first substrate (1), A2) large-area application at least one organic layer (2) on the first substrate (1) (by means of a coil coating line 90) and A3) separating the first substrate (1) with the at least one organic layer (2) in a plurality of functional layers stack (10), B) providing a second substrate (5), which has a lower flexibility and a higher impermeability to moisture and oxygen than the first substrate (1), and C) applying the (at least one of the plurality of functional layer stack 10) facing away from one of the organic layer (2) surface (11) of the first substrate (1) on the second substrate (5).
