Abstract
A plate-shaped component includes a transparent cover plate and a planar back element attached to the cover plate. The cover plate has a front surface facing the external environment and a back surface facing the back element. At least one surface selected from the front and back surfaces has at least one structured region, and at least one color filter layer for reflecting light within a predetermined wavelength range is arranged on the at least one surface selected from the front and back surfaces. The at least one structural region is perpendicular to the plane of the cover plate. The at least one color filter layer includes at least one refractive layer having a refractive index of greater than 2.5 in the wavelength range from 400 nm to at least 700 nm and an extinction coefficient of at least 0.2 below 450 nm and less than 0.2 above 700 nm.
