1. A microcavity electrophoretic display comprising microcapsules, each microcapsule having walls defining microcavities, the microcavities containing a fluid and first, second and third types of particles dispersed in the fluid, each of the first, second and third types of particles having an unshuttered state, in which the particles occupy substantially the entire area of the microcavity, and a shuttered state, in which the particles occupy only a minor proportion of the areas of the microcavity, the first, second and third particles being of differing colors and differing in dielectrophoretic or electro-osmotic properties such that the first, second and third types of particles can be moved between their unshuttered and shuttered states independently of one another.
