摘要： An electrophoretic display sheet comprising a display layer, a first electrode, and second electrodes. The display layer has a plurality of reservoir portions filled with a dispersion liquid containing particles. Each of the plurality of reservoir portions has predetermined positions. When an electric field having a direction is generated by applying a voltage to between the first electrode and the second electrodes, the particles are locally gathered to the predetermined positions of each of the plurality of reservoir portions so as to make rows of the particles along the direction of the electric field in the dispersion liquid. The electrophoretic display sheet is capable of exhibiting both superior responsiveness (responsibility) and superior color display performance with high contrast in changing a display color.

摘要： A display device comprises a microcapsule-containing layer including a plurality of microcapsules. A variation of the outer diameters of the microcapsules can be defined by an average value and a CV value. Each of the microcapsules is comprised of: a shell having an inner surface; contact particles electrically charged and provided within the shell in an contact state that the contact particles are in contact with the inner surface of the shell; and a scattering body for scattering light; or a colored particles having a different hue from the hue of the contact particles. The display device further comprises a pair of electrodes that when an electrical voltage is applied to between the pair of electrodes, electrical fields to act on the contact particles are generated. The average value of the outer diameters of the microcapsules is in the range of 20 to 60 μm, and the CV value of the outer diameters of the microcapsules is 20% or less. In a case where the electrical voltage is applied to between the pair of electrodes, the contact particles are moved along the inner surface of the shell while maintaining the contact state with the inner surface of the shell.
