An electric display device of the type wherein a dispersion liquid comprising
at least a dispersion medium and electrophoretic particles is disposed in a space
defined by a substrate, a partition wall disposed on the substrate, and a sealing
film disposed on an upper end portion of the partition wall is produced through
a process including a step of disposing a sealing film precursor, comprising a
polymerizable compound, supported by a supporting member on both an exposed surface
of the dispersion liquid and at least a part of the upper end portion of the partition
wall in a state that the dispersion liquid is filled between adjacent partition
walls, and a step of polymerizing the polymerizable compound to form the sealing film.
