In a process for the production of a plate, in particular a motor vehicle licence plate, in which at least a layer sequence forming an electroluminescence flat capacitor () and a reflection film (') are applied to a carrier (), a reflection film (&#x2032;) is selected whose reflection value is higher than the maximum value permitted by statute, and said reflection value is reduced by further production steps to such an extent that it is below the maximum value permitted by statute.

Method for producing a plate

A plate such as a motor vehicle licence plate comprises a casing which includes a flat rear wall surrounded by a forwardly projecting edge defining a light transmission opening, through which a flat symbol carrier extending parallel to the rear wall of the casing is visible. The symbol carrier has regions of differing transparency to represent symbols thereon. An electrically activatable light film between the rear wall and the symbol carrier shines light through the symbol carrier from the rear. To provide retroreflective properties, arranged in front of the light film and parallel thereto is a film which extends at least over considerable parts of the area of the light transmission opening and which is at least partially transparent for the light from the rear and which is retroreflective for light impinging thereon from the exterior. A light cover which is transparent at least in region-wise manner closes the light transmission opening. A rough layer is provided between the inward surface of the light cover and the surface that is theretowards of the retroreflective film.
