Abstract
The electrophoretic multi-color display device has a plurality of cells (″, . . . ) with an electrophoretic medium () and pixel electrodes (, . . . ) for selecting a subgroup of cells. A color filter array () is associated with the pixel electrodes. The color filter array () and the pixel electrodes (″, . . . ) are provided at the same side of the electrophoretic medium (). Preferably, the cells (″, . . . ) of the color filter array () are arranged according to a matrix and are disposed along lines registering with the pixel electrodes (″, . . . ). Preferably, an insulating material () with a relatively low refractive index is provided between the pixel electrodes (″ . . . ) and the color filter array (). Preferably, the insulating material () is selected from the group formed by a fluor-polymer, a low-dielectric inorganic film and a low-dielectric nano-porous film.
