Electroluminescent device and method for the production of the same

A method for producing an electroluminescent device, comprising the steps of:

• providing a transparent substrate on one surface of which a transparent conductive layer is applied,
• placing a luminescent layer on the transparent conductive layer by a coating process so that the width of the luminescent layer is smaller than that of the transparent conductive layer to form a luminescent layer carrying substrate,
• placing a masking on an exposed part of the transparent conductive layer of the luminescent layer-carrying substrate, which part has no luminescent layer, in the lengthwise direction of the transparent substrate, wherein the masking has a width smaller than that of the exposed part carrying no luminescent layer, and
• applying a conductive material onto the luminescent layer-carrying substrate, whereby forming a rear electrode thereon, and a buss that is electrically in contact with neither the luminescent layer nor the rear electrode due to the presence of the masking or the exposed part from which the masking is removed.

A method for producing an electroluminescent device, comprising the steps of:

• providing a transparent substrate on one surface of which a transparent conductive layer is applied,
• placing a masking on the surface of the transparent conductive layer to cover a buss-forming area, on which a buss is formed, with the masking, so that a buss-forming area having the applied masking and a masking-free area having no masking are formed on the transparent conductive layer,
• placing a luminescent layer on the masking-free area of the transparent conductive layer by a coating process to form a luminescent layer-carrying substrate,
• applying a conductive material onto the luminescent layer-carrying substrate to form a rear electrode on the luminescent layer,
• removing at least a part of the masking to expose the buss-forming area, and then
• applying a conductive material onto the exposed buss-forming area whereby the rear electrode is formed and the buss is electrically in contact with neither the luminescent layer nor the rear electrode due to the presence of the masking or the exposed part from which the masking is removed.
