    摘要: A display device for an interior of a motor vehicle has an opaque decorative layer with a display side and a rear side. The opaque decorative layer has at least one opening which extends through the opaque decorative layer from the rear side as far as the display side and which is filled with a light-guiding filling material. At least one illumination source is arranged in the region of the rear side of the opaque decorative layer in such a way that the illumination source emits light through the opening with the light-guiding filling material from the display side of the opaque decorative layer into the interior.
