  • a substantially transparent and electrically conductive layer is arranged with peripheral bus bar.
  • the EL layer of usually microencapsulated zinc sulfide electroluminophores is homogeneously dispersed in a polymeric matrix, preferably based on polyurethanes and such permanently elastic polymers arranged.
  • the EL layer can have a desired emission color by selecting or mixing the EL pigments. It is also possible to incorporate color-converting dyes and / or pigments (Stokes shift) and, for example, the emission color white can be achieved in this way. Since such conversion admixtures usually have an intrinsic color in the range pink-pink to orange, a thin layer of, for example, titanium dioxide dispersed in a polymeric matrix can be placed over it and can be achieved such a whitish surface.
  • the EL layer or in the polymeric matrix it is additionally possible to add long luminescent pigments.
  • inexpensive zinc sulfidic afterglow pigments can be used, and for a slower rechargeable afterglow layer, rare earth doped aluminates or silicates pigments are preferably used which then have an afterglow time of up to 2,000 minutes (observable for the dark-adapted eye and fully charged afterglow pigments) and have over it.
  • the EL layer is usually produced by screen printing. By this type of production also point-like EL elements are basically printable. By such a grid of EL points or small geometrical shapes, the active EL area can be reduced and the EL power supply can be made smaller.
  • the back electrode After the insulation layer or the usually two printed insulation layers comes the back electrode. This can be formed directly in connection with the insulating layer or separately by means of lamination of a corresponding electrode arrangement.
  • the back electrode may be integrated in the EL layer sequence (2) or it may be formed by the backside conductive pattern (15) on the substrate (10). This results in a particularly flexible and thin structure.
