Liquid crystal display device for total reflection switching with fluorescent dye addition.

Bias dependences for reflectivity curves were measured in the total reflection range for several liquid crystals, and orientation near the boundary was investigated. Incident angle dependences of the transient response for total reflection ON and OFF switching were measured. Fluorescent dye addition effects for total reflection switching were investigated. Using a mixture of the fluorescent dye (coumarin 6) and MBBA + BBCA, a novel display device for a wide viewing angle has been successfully demonstrated.
