摘要： PROBLEM TO BE SOLVED: To provide high image quality even in the case of writing a new image to a display medium, which has been displaying and retaining a pre-written image for a long period of time, and displaying the new image. SOLUTION: In driving an image display medium which is constructed by sealing a colored and charged particle group between a pair of substrates placed opposite to each other via a gap, and in which the display density is varied by transferring the colored and charged particle group between the pair of substrates corresponding to an electric field formed with the voltage applied between the pair of substrates, charge of the colored and charged particles is recovered by setting a period T L , a magnitude of an applied voltage and an application time period and applying an alternating voltage to all pixels of the image display medium (the first refresh period), and at the same time adhesion between the colored and charged particles and the substrate or that among the colored and charged particles themselves are broken to strip them from one another. Subsequently by applying an alternating voltage to all pixels of the image display medium with a period corresponding to a comparatively high frequency (several hundreds Hz) (the second refresh period), density of the entire surface of the image display medium is uniformized, and subsequently an image is written to (the driving period).

摘要： PROBLEM TO BE SOLVED: To provide an image display medium and an image display device in which spreading out of pixels is reduced in producing image display with simple matrix driving.
SOLUTION: The image display medium is constructed by sealing in black particles 18 and white particles 20 between a display substrate and a back substrate. A plurality of linear electrodes 403A1-A3 are formed on the display substrate 14. A plurality of linear electrodes 404B1-B3 are formed on the back substrate 16 in a direction where the electrodes 404B1-B3 perpendicularly intersect the electrodes 403A1-A3. Widths of the backside electrodes 404B1-B3 are smaller than those of the display side electrodes 403A1-A3. When a voltage of -100V is applied to the display side electrode 403A1 and a voltage of +100V is applied to the backside electrode 404B2, particles fly in an oblique direction due to a potential difference generated with respect to adjacent backside electrodes 404B1, B3, however, the electric field is weak because a distance between the backside electrodes is long. As a result, the spreading out of the pixels is suppressed.
