Abstract
A reflective color liquid crystal comprising a guest-host liquid crystal display, a color filter and a reflector. The reflector is a simple mirror-like reflection surface. The color filter is manufactured with a pigment dispersion method. The particle size of the pigment is reduced to provide strong light forward scattering and weak light back scattering. The color filter provides light colors for the display as well as light scattering to increase the viewing angle for the display.
