Abstract:
1. A display device comprising: a microcapsule-containing layer including a plurality of microcapsules each having an outer diameter, wherein a variation of the outer diameters of the plurality of microcapsules can be defined by an average value and a CV value, and wherein each of the plurality of microcapsules comprised of: 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; wherein the average value of the outer diameters of the plurality of 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, and wherein 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.
