[Papers] Achromatic Dye-type Polarizer for Paper White Reflective Liquid Crystal Displays

Abstract

We have developed the achromatic polarizer using novel dichroic pigments. We established a method to control the light absorption, dichroic ratio, and alignment direction of dichroic pigments and successfully achieved high transmittance uniformity in visible wavelength range in both parallel and crossed states. This polarizer results in development of the low power monochrome-type reflective liquid crystal display with high reflectivity, paper white and motion picture capability.
