Abstract:
An electrophoretic display sheet capable of increasing pressure resistance and bleed resistance of microcapsules and constructing an electrophoretic display device stably operable for a long period of time, a highly reliable electrophoretic display device and a highly reliable electronic apparatus are provided. The electrophoretic display sheet includes a base substrate having one major surface, and a microcapsule-containing layer provided on the side of the one major surface of the base substrate and having one major surface, the microcapsule-containing layer including a plurality of microcapsules, each of the microcapsules having a shell and an electrophoretic dispersion liquid containing at least one kind of electrophoretic particles and encapsulated into the shell, wherein the microcapsules exist in a generally spherical shape within the microcapsule-containing layer.
