Various type color PDLC structures have been characterized on a glass and a plastic substrate for reflective mode color display. The standard PDLC and the black diachronic dye mixed PDLC structure with color filter (RGB) show a good black state with high color purity and 256 gray levels, even though both structures have a dark color images. Color dichroic dye (RGB/CMY) mixed PDLC cells promise a good white reflectance. The problem of using color dye system is the enhancement of a poor black state. Using new CMY color based filter with black dye PDLC shutter structure can improve a white state with a proper color vision.
