Abstract
A display apparatus for a vehicle and a method for producing the display apparatus are described. The display apparatus comprises a transparent plastic plate having a front side, a rear side, and an edge surface surrounding the plastic plate. The display apparatus has a switchable light source of visible light directed onto the edge surface of the plastic plate. The plastic plate has transparent display elements that are disposed as limited zones inside the plastic plate and have light-sensitive dopant particles. When the light source is switched on, the dopant particles scatter the light so that the display elements become visible from the front side.
