Abstract

A shaped part includes a decorative layer having a front/visible side, and a rear opposing side, a light guide assembly arranged on the rear side of the decorative layer for illuminating and/or backlighting the decorative layer, and one or more light sources. Light (L) emanating from the light source(s) can be input into the light guide assembly. The light guide assembly has a light guide layer with a front side and a rear side. An at least sectionally translucent mirror film is arranged on the front side of the light guide layer and a rear-side mirror film is arranged on the rear side of the light guide layer. Light (L) emanating from the light source(s) and input into the light guide layer of the light guide assembly can be partially reflected on the mirror films, and thus propagates in the light guide layer.
