The aim is to provide backlighting in a liquid-crystal display unit for a display and/or operator control unit, in particular on a domestic appliance. To achieve this, a backlighting layer, to which at least one backlighting source can be coupled, is located beneath an LCD layer and at least one supplementary backlighting layer is located beneath the backlighting layer. The supplementary layer can be coupled to at least one additional backlighting source assigned to the layers and permits the respective supplementary backlighting layer to emit light from the additional backlighting source(s) in respective defined masked zones through the backlighting layer and through the LCD layer.
