Abstract:
The electrophoretic display device includes: an electrophoretic layer which is disposed between first and second substrates disposed to face each other and has a plurality of first electrically-charged particles colored into a first color, a plurality of second electrically-charged particles colored into a second color, and a dispersion medium which retains the first and second electrically-charged particles; first and second pixel electrodes provided on the first substrate; an opposite electrode provided on the second substrate; and a reflective electrode provided at a position on the first substrate side rather than on the electrophoretic layer, wherein the first electrically-charged particle has permeability in a first wavelength region and absorbability in the other wavelength regions, and the second electrically-charged particle has reflectivity in a second wavelength region and absorbability in the other wavelength regions.
