Abstract
An electrophoretic device includes a fiber layer, an electrophoretic particle configured to migrate through a gap in the fiber layer, and a partition wall extended in a thickness direction of the fiber layer to separate the fiber layer into a plurality of migration cells. The partition wall includes a cured body of a curable resin, and the cured body includes a constriction part between both end portions of the fiber layer in the thickness direction.
