Patent ID: 7557502

Claim:
An organic electroluminescent device comprising: a transparent substrate; a cover plate that includes a first side facing the transparent substrate, a second side opposed to the first side, and multiple layers between the first and second sides; at least one electroluminescent element comprising an organic electroluminescent layer arranged between the transparent substrate and the cover plate; and a seal that is configured to join the transparent substrate and the cover plate, wherein: the cover plate includes a material selected from the group of glass-ceramic and ceramic materials, a first conductive pattern is formed on the first side of the cover plate and includes first contact pads, a second conductive pattern is formed on one of the sides of the cover plate and includes second contact pads; the first and the second conductive patterns are electrically interconnected via conductors, each conductor extending on at least one internal surface of the multiple layers inside the cover plate, the electroluminescent element is present on the transparent substrate, and is provided with an electrode pattern of anode and cathode that is interconnected to the first contact pads in the first conductive pattern on the first side of the cover plate, the electrode pattern of anode and cathode comprises contact pads, which are interconnected to the first contact pads by means of a solder connection, and the seal means comprises a solderable metal, the seal and the solder connection being soldered in one process step.
