Object To uniformly arrange microcapsules in an electrophoretic display device to obtain an electrophoretic layer of good quality. Solving Means In applying an application material 7 containing microcapsules 7 dispersed therein on a transparent film 1 on which an ITO electrode 2 is formed, the application is performed under a condition in which a voltage with polarity opposite to the electrophoretic particles in the microcapsules 7a is applied to the ITO electrode 2. Since the electrophoretic particles in the microcapsules 7a and the ITO electrode 2 are attracted to each other, the microcapsules 7a are attracted to the ITO electrode 2. Therefore, the microcapsules 7a in an upper layer of overlapping layers easily enter the spaces between the microcapsules 7a in a lower layer. It is thus possible to avoid overlapping of the microcapsules 7a, and obtain an electrophoretic layer 3 having the microcapsules uniformly arranged therein.
