An electrophoresis display capable of displaying colors, yet having high contrast and a high reflectance on displaying white color. The electrophoresis display device includes a dispersion medium containing a liquid crystal and electrophoretic particles made of titania, etc. being dispersed in the dispersion medium, wherein the dispersion medium contains a dichroic coloring matter having dichroism with a high dichroic ratio as a first coloring matter and a dichroic coloring matter having dichroism with a low dichroic ratio and/or an isotropic coloring matter as a second coloring matter, provided that the first coloring matter and the second coloring matter have complementary colors each other. In this manner, white, black, and color displays are realized by a single capsule. |
