Abstract
A system (apparatus and process) for producing an electrophoretic (display) device is provided for allowing production of such a device wherein electrophoretic particles in the dispersion liquid are easily and evenly distributed to respective cells (pixels) between two substrates of the device even in the case of a very small gap between the two substrates or the case of using a flexible substrate. The system includes a storage unit for a dispersion liquid containing the charged phoretic particles dispersed therein, a stirrer for stirring the dispersion liquid, a substrate-holder for holding the substrate in the dispersion liquid, and a voltage source for applying a voltage to the electrodes formed on the substrate thereby depositing the electrophoretic particles on the electrodes.
