Method for processing a transparent cover plate and cover plate

A method for processing a transparent cover plate for a flat body, comprising the following steps of:

• a) providing the transparent cover plate having an outer side and an inner side opposite to the outer side, wherein the outer side is to face an external environment, and the transparent cover plate comprises a structured area with a light-scattering structure in at least one cover plate surface selected from an outer surface and an inner surface of the transparent cover plate, or alternatively the structured area is formed;
• b) forming of at least one first optical interference layer on a part of a cover plate side selected from the outer side and the inner side, comprising:
• b1) applying a mask to the transparent cover plate, wherein, in a vertical view through the transparent cover plate, the mask does not cover a first area of the at least one cover plate surface of the cover plate side and covers a second area of the at least one cover plate surface of the cover plate side, and the first area and the second area are arranged to overlap the structured area to be formed,
• b2) applying the at least one first optical interference layer for reflecting a light within a predetermined wavelength range to the transparent cover plate on a selected cover plate side, wherein the at least one first optical interference layer is applied in a perpendicular view through the transparent cover plate (10) in overlap with the mask and in overlap with the first area of the at least one cover plate surface;
• b3) removing of the mask, wherein the at least one first optical interference layer overlapping the mask in the vertical view, is also removed.
