Abstract: An electrophoretic display device comprises a first substrate and a second substrate positioned to face each other. A first electrode is so mounted to the first substrate as to face second and third electrodes. The second and third electrodes have an area smaller than that of the first electrode. Also, the distance between the second and third electrodes is set shorter than the distance between the second and first electrodes and the distance between the third and electrodes. A suspension dispersing charged fine particles in an insulating liquid medium is interposed between the first electrode and the second and third electrodes. An AC voltage is applied between the second and third electrodes, and a DC voltage is applied between the first electrode and the second and third electrodes. Thus, the migration of charged fine particles are controlled in accordance with the dielectrophoretic and electrophoretic forces.

Abstract: An electrophoretic display device comprises substrates faced to each other so as to form a pixel space therebetween. A first electrode group including control electrode segments is formed on the substrate, and a second electrode group including a counter electrode segment is formed on the substrate. A dispersion liquid of colored and charged fine particles dispersed in an insulating liquid is charged in the pixel space. The fine particles are collected on the first and second electrode groups so as to permit different colors to be displayed on the pixel. A first voltage is applied to a control electrode segment and a second voltage applied to the other control electrode segments so as to cause the colored and charged fine particles to be migrated at a uniform migration speed to the control electrode segments, thereby collecting the colored and charged fine particles on the control electrode segments.

Abstract: In this invention, as a basic structure, an impedance element is connected in series to a liquid crystal layer (liquid crystal capacitance) of each pixel. The impedance of the impedance element is varied in accordance with a display signal. The resistance values of variable resistance elements are varied in accordance with a display signal being held by a display signal holding means that is provided in each pixel, whereby the impedance of the impedance element varies in accordance with the resistance states of the variable resistance elements. If an AC voltage is applied across the basic structure, an AC voltage produced by voltage division in accordance with the impedance of the impedance element is applied to the liquid crystal layer. Therefore, the AC voltage applied to the liquid crystal layer and hence the gradation level of the liquid crystal layer can be controlled by adjusting the impedance of the impedance element in accordance with a display signal.
