Abstract
The liquid crystal day & night mirror with excellent reflective characteristics has been developed.
The day & night mirror using Guest-Host liquid crystal devices improves the performance of rear view mirrors.
Effects of primary factors on reflective characteristics of the liquid crystal day & night mirror have been investigated. Results are as follows.
-
(1)
The reflective characteristics at wavelength of about 555 nm are important for the selection of liquid crystals and dichroic dyes.
-
(2)
The reflective characteristics are improved by decreasing the reflectivity of glass substrate.
-
(3)
The reflective characteristics are improved by increasing the reflectivity of reflector.
