Реферат: Flat waveguide has a light coupling surface, a reflection surface and a light decoupling surface lying opposite the reflection surface. The reflection surface contains agents for homogenizing the luminance on the light decoupling surface. A light-impermeable material having a degree of covering that varies over the reflection surface is applied to the reflection surface of the waveguide. An Independent claim is also included for a process for the production of a waveguide comprising printing a pattern of a light-impermeable material to one surface of a body made of light-permeable material.
