Abstract
A display device for the interior of a vehicle comprises light sources, light guides, and holograms. The light guides are arranged next to one another and each has an entrance surface and a reflective area. Each light source emanates light that enters the entrance surface of an associated light. At least one of the holograms is arranged at or in each light guide. The light emanated by each light source enters the entrance surface of the associated light guide in a direction of the reflective area of the associated light guide, is reflected by the reflective area of the associated light guide in a direction of the hologram of the associated light guide, and interacts with the hologram of the associated light guide.
