Abstract
The invention relates to a lighting element, wherein at least one organic light-emitting diode is formed at an optically transparent substrate as a layer structure. In the lighting element in accordance with the invention, at least one organic light-emitting diode is formed at an optically transparent substrate as a layer structure. The at least one organic light-emitting diode and the substrate are connected to a circuit board and electric contact elements for the connection of the electrodes of the organic light-emitting diode(s) are present at the surface of the circuit board. The surface of the circuit board facing in the direction of the organic light-emitting diode(s) is provided over its full area with a metallic coating as a permeation barrier. The metallic coating is only breached by electric insulators formed about the contact elements.
