An optoelectronic device comprising:
- a covering layer, a first electrode, a functional layer stack arranged between the covering layer and the first electrode and a plurality of spacers, wherein
- the functional layer stack has an organic active layer that generates electromagnetic radiation,
- the first electrode has conductor tracks with branching points,
- the spacers are each arranged on one of the branching points, and
- the functional layer stack is arranged in places between the covering layer and the spacers.
A method of producing an optoelectronic device comprising a covering layer, a first electrode with conductor tracks and branching points, a functional layer stack and a plurality of spacers, the method comprising:
- a) providing a carrier body;
- b) forming the first electrode on the carrier body;
- c) forming the spacers on the branching points;
- d) applying the layer stack both to the first electrode and the spacers;
- and
- e) applying the covering layer, wherein the functional layer stack is arranged in places between the covering layer and the spacers.
An optoelectronic device comprising:
- a covering layer, a first electrode, a functional layer stack arranged between the covering layer and the first electrode and a plurality of spacers, wherein
- the functional layer stack has an organic active layer that generates electromagnetic radiation,
- the first electrode has conductor tracks with branching points,
- the spacers are each arranged on one of the branching points,
- the functional layer stack is arranged in places between the covering layer and the spacers, and
- the spacers are each spaced from one another in the lateral direction, and the spacers each cover exactly one of the branching points.
