Abstract
An electroluminescent device. Providing atmosphere lighting is possible by an electroluminescent layer, and a first electrode layer arranged on a of the first side of the electroluminescent layer and a second electrode layer arranged on a second side, opposing the first side of the electroluminescent layer, for supplying charges to the electroluminescent layer, at least one first contact element for contacting the first eletrode layer with a charge supply, at least one second contact element for contacting the second electrode layer with the charge supply, wherein the first and second electric contact elements are arranged asymmetrically to each other such that the intensity of light emitted from the electroluminescent layer varies across its area.

An electroluminescent device comprising
- an electroluminescent layer,
- a first electrode layer arranged on a first side of the electroluminescent layer and a second electrode layer arranged on a second side, opposing the first side of the electroluminescent layer, for supplying charges to the electroluminescent layer,
- at least one first contact element for contacting the first electrode layer with a charge supply, and
- at least one second contact element for contacting the second electrode layer with the charge supply,
- wherein the first and second contact elements are arranged and configured relative to each other such that the intensity of light emitted from the electroluminescent layer varies across its area and wherein at least two of the first contact elements are arranged as rows extending from one edge of the first electrode layer to the other edge and at least two of the second contact elements are arranged as columns extending from one edge of the second electrode layer to the other edge and perpendicular to the first contact elements arranged as rows.
