Abstract
A method of and device for controlling a reflective color of a photonic crystal display device, capable of precisely controlling the distance between particles to display RGB full colors covering desired wavelength ranges. The method and device include using a mixed dispersion medium containing two or more kinds of solvents having different dielectric constants as a dispersion medium for a photonic crystal in a composition for a photonic crystal display device of which colors are controlled through the application of an electric field.
