In an electrophoretic display apparatus, a surface of the charged
particle, the dispersion medium, and a surface of an inner wall on which
charged particles are to be deposited satisfy any one of the following
(A) to (D): (A) the charged particle surface is hydrophilic, the
dispersion medium is hydrophobic or is hydrophobic and lipophobic, and
the inner wall surface is hydrophilic; (B) the charged particle surface
is hydrophobic, the dispersion medium is hydrophilic or is hydrophobic
and lipophobic and the inner wall surface is hydrophobic; (C) the charged
particle surface is hydrophobic and lipophobic, the dispersion medium is
hydrophobic or hydrophilic, and the inner wall surface is hydrophobic,
with the proviso that when the dispersion medium is hydrophobic, a
difference in hydrophobicity between the dispersion medium and the
charged particle surface is larger than a difference in hydrophobicity
between the inner wall surface and the charged particle surface; and (D)
the charged particle surface is hydrophobic and lipophobic, the
dispersion medium is hydrophobic or hydrophilic, and the inner wall
surface is hydrophobic and lipophobic.
