Abstract

A display unit includes a layer with a plurality of sub-regions which are arranged adjacently to one another along an illuminated edge of the layer. A corresponding number of symbols are arranged in the sub-regions. The display unit additionally has a plurality of light sources. The said light sources are arranged adjacently to one another along the illuminated edge of the layer. Each light source is configured to emit light into the respective sub-region of the layer via the illuminated edge of the layer. The display unit additionally has a limiting element which is arranged between the illuminated edge of the layer and the light sources and which is configured to limit the light emitted from the light sources for each sub-region such that the symbol in the respective sub-region is illuminated in a selective manner by the light sources.
