Abstract:
1. A manufacturing apparatus for manufacturing a display medium, the display medium comprising a transparent first substrate that constitutes a display surface; a second substrate that opposes an underside surface side of the display surface of the first substrate and separates from the underside surface with a prescribed gap; an electrophoretic layer that is disposed in the prescribed gap and has a liquid in which a plurality of charged particles are dispersed; a first electrode that is disposed between the electrophoretic layer and the first substrate and has a prescribed shape; and a second electrode that is disposed between the electrophoretic layer and the second substrate, wherein voltage applied across the first electrode and the second electrode causes the charged particles in the electrophoretic layer to move toward either an area facing the first electrode or an area facing the second electrode for producing a display corresponding to the shape of the first electrode, the manufacturing apparatus comprising: an image data storing unit that stores image data for text or image to be displayed on the display medium; an electrode pattern generating unit that generates an electrode pattern based on the image data stored in the image data storing unit so that when the text or image is configured of a plurality of independent regions, the electrode pattern has a plurality of integrally and electrically connected electrodes corresponding to a plurality of regions; an electrode forming unit that forms the first electrode on either an electrophoretic medium integrally configured of the second substrate, the second electrode, and the electrophoretic layer or the first substrate based on the electrode pattern generated by the electrode pattern generating unit; and a bonding unit that bonds the electrophoretic medium to the first substrate after the electrode forming unit has formed the first electrode.
