Abstract

A cover panel, for at least partially transparently covering at least one display instrument in a vehicle, has a microstructure applied on at least one surface. The microstructure is suitable for scattering visible light which is incident on the cover panel. The at least one window region of the cover panel is cutout from the microstructure. A method for manufacturing such a cover panel uses a molding tool with an applied microstructure matrix for forming a microstructure on a part of the molding tool which is assigned to a surface of a molded cover panel. The parts of the molding tool which are assigned to window regions are cut out from the microstructure matrix.
