Paper Abstract

The first guest host (GH) display was suggested in 1968 by Heilmeier and Zanoni . They proposed dissolving pleochroic dye molecules in a nematic liquid crystal (LC). A pleochroic dye is characterized by unequal absorption of two perpendicularly polarized beams of incident light. This anisotropic absorption can be described by two absorption constants. In the case of linear dichroism these absorption cons- tants are related to directions of polarization, respectively parallel and perpen- dicular to the transition moment of the dye molecule.
