Claim 6:
7. The method according to claim 1, wherein the structure area comprises following features of:
perpendicular to a plane of the transparent cover plate wherein a height profile comprising mountains and valleys, wherein an average height difference between the mountains and valleys is at least 2 μm,
at least 50% of the structured area is composed of segments inclined to the plane of the transparent cover plate, wherein, relative to the plane of the transparent cover plate, at least 20% of the segments have an angle of inclination in a range of greater than 0° to a maximum of 15° and at least 30% of the segments have an angle of inclination in a range of greater than 15° to a maximum of 45°, wherein
when the inner surface has at least one structured area, the segments of the at least one structured area of the inner surface are each flat, have a segment area of at least 1 μm2 and a mean roughness of less than 15% of a layer thickness of the at least one first optical interference layer on the inner surface.
