Organic Optoelectronic Device and Method for Producing an Organic Optoelectronic Device

An organic optoelectronic device, comprising:

• a first substrate, on which a functional layer stack having at least one first electrode, thereabove an organic functional layer and thereabove a second electrode is arranged;
• and
• an encapsulating arrangement which comprises a second substrate, on which a connecting material and a spacer facing the functional layer stack are applied and are fixedly connected to the second substrate;
• wherein the connecting material is arranged between the first substrate and the second substrate and mechanically connects the first and second substrate together;
• wherein the functional layer stack is enclosed by the connecting material in a frame-like manner;
• and
• wherein at least one of the first electrode or the second electrode comprises an opening, above which the spacer is arranged, the opening having a larger lateral dimension than the spacer.

A method for producing an organic optoelectronic device, the method comprising:

• providing a first substrate, on which a functional layer stack having a first electrode, thereabove an organic functional layer and thereabove a second electrode are arranged, wherein at least one of the first electrode and the second electrode comprises an opening;
• providing a second substrate;
• applying connecting material onto an upper side of the second substrate;
• applying a spacer onto the upper side of the second substrate;
• connecting the spacer to the second substrate by use of a sintering process thereby producing an encapsulation arrangement;
• and
• arranging the encapsulating arrangement on the first substrate so that the functional layer stack is enclosed by the connecting material and the spacer is arranged above the opening.
