Abstract:
An electrophoretic display sheet includes: a substrate; at least one kind of electrophoretic particles; an electrophoretic dispersion liquid containing the at least one kind of electrophoretic particles; a microcapsule having a shell for enclosing the electrophoretic dispersion liquid therein; a microcapsule-containing layer provided on a surface side of the substrate to contain the microcapsule; and a binder having a function of retaining the microcapsule and having viscosity under room temperature, the microcapsule-containing layer including the microcapsule and the binder; and the electrophoretic particles being contained in the electrophoretic dispersion liquid in a ratio of 30% to 60% wt. with respect to a weight of the electrophoretic dispersion liquid.
