In a white light LED, multicolor-emitting light emitter layers of macroscopic structure widths, whose emission spectra can be mixed to form white light, are arranged laterally next to one another on a first transparent electrode layer. The light emitter layers are preferably in strip form and have, for the purpose of simplifying production, macroscopic dimensions that can be resolved by the eye. The thickness of a light-scattering substrate is chosen such that the radiation beams emitted by the light emitter layers are at least partly superposed on the light exit surface of the light-scattering substrate, thereby creating the optical impression of a white light source. |
