Abstract: The invention in general relates to the single-sided wet chemical surface modification as in particular the coating of flat substrates. In particular, the present invention relates to a method as well as to an apparatus for the coating of substrates in the course of the production of thin film solar cells or modules made from glass, metal, or plastic with metallic compounds such as i.e. cadmium sulphide or zinc sulphide.

Abstract: A display device is provided that includes a luminous element and a laterally structured luminous surface. The laterally structured luminous surface has at least one region that is capable of illumination, as well as at least two light-reflecting layers that are spaced apart from one another and between which light emitted by the luminous surface is reflected back and forth. At least one of the two light-reflecting layers are semitransparent, and at least one of the two light-reflecting layers is arranged at a distance from the luminous element.
