Abstract
A process for producing a sheet for electrophoretic display including steps of: (a) continuously running a strip-shaped substrate sheet in which an electrically conductive layer is formed on a substrate film, and coating, on the substrate sheet, a coating solution containing a microcapsule for electrophoretic display, using a coating apparatus of a kiss reverse coating system having a coating roll in which a gravure pattern is discontinuously formed in an axial direction of an external circumferential surface; and (b) drying the coating solution to form a layer containing the microcapsule on the electrically conductive layer to obtain a sheet for electrophoretic display in which a microcapsule supporting part on which the microcapsule is supported, and an electrically conductive layer exposing part on which the electrically conductive layer is exposed are alternatively arranged in a width direction of the sheet.
