The electrophoretic multi-color display device has a plurality of cells
(10, 10', 10'', . . . ) with an electrophoretic medium (14) and pixel
electrodes (11, 11', 11'', . . . ) for selecting a subgroup of cells. A
color filter array (13) is associated with the pixel electrodes. The
color filter array (13) and the pixel electrodes (11, 11', 11'', . . . )
are provided at the same side of the electrophoretic medium (14).
Preferably, the cells (10, 10', 10'', . . . ) of the color filter array
(13) are arranged according to a matrix and are disposed along lines
registering with the pixel electrodes (11, 11', 11'', . . . ).
Preferably, an insulating material (17) with a relatively low refractive
index is provided between the pixel electrodes (11, 11', 11'' . . . ) and
the color filter array (13). Preferably, the insulating material (17) is
selected from the group formed by a fluor-polymer, a low-dielectric
inorganic film and a low-dielectric nano-porous film.
