METHOD FOR CONTROLLING REFLECTIVE COLOR OF POLYMERIC COLLOIDAL PHOTONIC CRYSTAL DISPLAY DEVICE USING MIXED DISPERSING MEDIA

摘要

In a composition for a photonic crystal display device whose color is controlled by applying an electric field, the present invention relates to a method for controlling a reflective color of a polymeric colloidal photonic crystal display device, which can realize RGB full color including a wavelength of a desired range, by fine tuning of particle intervals by using a complex dispersion medium where a dispersion medium of a photonic crystal includes more than two kinds of solvents whose dielectric constants are different.
