Abstract
An electrophoretic display device distributes an electrophoretic liquid mixture containing electrophoretic particles to respective pixels in substantially equal amounts, thereby obviating a display density fluctuation due to a difference in distributed amount of the electrophoretic particles at the respective pixels. The equal distribution is performed through a process including the use of a temporary adsorbing member carrying the electrophoretic particles in an electrostatically adsorbed form in a pattern corresponding to an arrangement pattern, followed by transfer of the electrophoretic particles to the respective pixels, or a process including distribution of a distribution liquid containing the electrophoretic particles to the respective pixels followed by a step of adding the dispersion liquid.
