ELECTROPHORETIC DISPERSION LIQUID, ELECTROPHORETIC SHEET, ELECTROPHORETIC DEVICE, AND ELECTRONIC APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an electrophoretic dispersion liquid including electrophoretic particles that can exhibit excellent display characteristics in an electrophoretic device, and a highly reliable electrophoretic sheet, electrophoretic device, and electronic apparatus using the electrophoretic dispersion liquid.SOLUTION: An electrophoretic dispersion liquid of the present invention contains first electrophoretic particles of a scattering system including an ionic group on the surface, second electrophoretic particles of a colored system including a polarization group on the surface, and a dispersion medium. The ionic group is preferably an acidic group and has a cyclic structure forming the acidic group and salt. The polarization group is preferably an organic group including a main skeleton and a substituent group coupled to the main skeleton.SELECTED DRAWING: None
