Abstract

A display device comprises an opaque display face on the surface of a transparent plate (3), a multiplicity of transparent or transluscent letter markings (2) which are formed on the display face, reflecting regions (4) which are arranged on the rear surface of the transparent plate such that they correspond to the letter markings, and a light source (5) which is arranged near the transparent plate. <IMAGE>
