Abstract:
1. An apparatus for producing an electrophoretic display device having charged phoretic particles and a dispersion liquid medium for dispersing the charged phoretic particles disposed between a first substrate and a second substrate, said first substrate having a pair of electrodes formed thereon; said apparatus comprising: substrate-holding means for holding the first substrate; means for applying a voltage between the pair of electrodes on the first substrate; ejection means for ejecting a first dispersion liquid containing the charged phoretic particles dispersed therein onto the first substrate while said means for applying a voltage applies a desired voltage between the pair of electrodes on the first substrate; and means for applying a second dispersion liquid containing a lower concentration of charged phoretic particles than the first dispersion liquid onto the first substrate after ejection of the first dispersion liquid.
