Method of manufacturing a visualization element with polarization influence

摘要

The method involves applying at least one material with a polarization influencing effect to at least two adjacent areas of a substrate using a printing technique so that the applied material has a different polarization influencing effect in the adjacent areas. A material with a doubly refracting effect is applied so that the material has a different double refraction effect in adjacent areas. Independent claims are also included for the following: (1) a polarization-influencing observation element (2) and a display device for displaying freely programmable information.
