Abstract
This invention relates to an electrophoretic display comprising isolated cells of well-defined shape, size and aspect ratio which cells have internal sub relief structures and are filled with charged pigment particles dispersed in a dielectric solvent. The display shows an improved contrast ratio and resistance against shear and compression pressures. The display may have the traditional up/down switching mode, an in-plane switching mode or a dual switching mode.
