Electrophoretic element, display, and electronic device

摘要

An electrophoretic element includes an electrophoretic particle, and a porous layer formed of a fibrous structure having a non-electrophoretic particle with different optical reflection characteristics from optical reflection characteristics of the electrophoretic particle. A difference Delta1 (=A-B) between a solubility parameter value A of the fibrous structure and a solubility parameter value B of a particle surface of the electrophoretic particle is 2 or more and 5.2 or less.
