Abstract:
Provided is a method of producing an electrophoretic display sheet having a substrate and a microcapsule-containing layer disposed on one surface side of the substrate and including microcapsules and a binder holding the microcapsules, the microcapsules each composed of a shell and an electrophoretic dispersion liquid sealed in the shell and containing at least one type of electrophoretic particles. The method includes the step of forming the microcapsule-containing layer where the microcapsules are arranged in a single layer without overlapping in the thickness direction of the substrate by supplying a microcapsule dispersion containing the microcapsules and the binder onto the substrate and then pressurizing the microcapsule dispersion in the thickness direction of the substrate.
