Abstract

An electrophoretic device includes: an electrophoretic particle; a porous layer formed of a fibrous structure containing a non-electrophoretic particle having optical reflection characteristics different from those of the electrophoretic particle; and a dividing wall adjacent to the porous layer. The electrophoretic particle, the porous layer, and the dividing wall are in an insulating liquid. Volume resistivity of the fibrous structure is larger than volume resistivity of the insulating liquid, and volume resistivity of the dividing wall is larger than the volume resistivity of the insulating liquid.
