Abstract
The present invention is directed to a color display device in which each pixel can display at least five high-quality color states, and an electrophoretic fluid for such an electrophoretic display. In one aspect, the different types of particles exhibit different levels of attraction force to display different color states. In another aspect, the different types of particles exhibit different levels of mobility in different driving voltage ranges to display different color states.
