The present invention provides a display medium, comprising: a display
medium, comprising: a pair of substrates, at least one of the pair of
substrates having transparency; a particle group enclosed between the
pair of substrates, the particle group migrating between the pair of
substrates in response to an electric field formed between the pair of
substrates; a dispersion medium that is enclosed between the pair of
substrates and disperses the particle group; a porous member disposed
between the pair of substrates and having a plurality of pores that allow
passage of the particle group; and embedded members that partition the
porous member into specific regions and that are embedded inside at least
a part of the pores in the porous member that are present along the
direction in which the pair of substrates are opposed.
