Abstract:
1. A display sheet comprising: a display layer that includes: (1) a first display layer having multiple first containers each containing a first electrophoretic particle group, and (2) a second display layer disposed on one surface side of the first display layer and having multiple second containers each containing a second electrophoretic particle group; the first electrophoretic particle group includes: (1) first positively-charged particles that are positively charged, and (2) first negatively-charged particles that are negatively charged, the first positively-charged particles having a color different from the first negatively-charged particles; the second electrophoretic particle group includes: (1) second positively-charged particles that are positively charged and having the same color as that of the first positively-charged particles, and (2) second negatively-charged particles that are negatively charged and having the same color as that of the first negatively-charged particles; and an intermediate layer disposed between the first display layer and the second display layer, the intermediate layer being conductive in a thickness direction and nonconductive in a lateral direction when an x-axis and a y-axis are set so as to perpendicularly intersect each other in a planar view of the display layer, wherein each of the multiple first containers overlaps at least one of the multiple second containers in a planar view of the display layer, and when the x-axis and the y-axis are set so as to perpendicularly intersect each other in a planar view of the display layer, each of the multiple second containers partially overlaps at least one of the multiple first containers so as to shift from each other in at least one axial direction of the x-axis and the y-axis.
