Amorphous highly twisted nematic liquid crystal display devices have been prepared by a nonrubbing technique. The liquid crystals are injected into the cells in the isotropic phase and then cooled down to the nematic phase. Micro-domains of highly twisted nematic liquid crystals are formed during the cooling process. The twist angles of the micro-domains are controlled by the concentration of the chrial dopants. The transmission spectrum and the electro-optical characteristics of the devices have been measured. The experimental results show that the devices possess wide and uniform viewing angle characteristics (−51 to +52/ −49 to +48 degrees). The 4 × 4 optical matrix method has been applied to a model of randomly distributed multi-domains of highly twisted nematic liquid crystats. The theoretical results are in good agreement with the experiment.
