Abstract
Multicolor light-emitting layers (1, 2, 3), for example organic layers, having emission spectra which can be mixed to form a white light, are laterally juxtaposed on a first transparent electrode layer (7). Said light-emitting layers (1, 2, 3) are preferably strip-shaped and have macroscopic dimensions, visible to the naked eye, for simplifying the production thereof. The thickness of the light-scattering substrate (4) is therefore selected, such that the ray beams, emitted from the light-emitting layers (1, 2, 3), at least partially superimpose on the light output surface of the substrate (4), in order to produce the optical effect of a white light source.
