Abstract:
Disclosed is an electrophoretic composition including a dye, a non-water-soluble dispersion medium, and charged particles, wherein the dye includes in a molecule thereof at least two color forming moieties including a first color forming moiety and a second color forming moiety, the first color forming moiety having a maximum absorption wavelength that is the shortest maximum absorption wavelength among the at least two color forming moieties, the second color forming moiety having a maximum absorption wavelength that is the longest maximum absorption wavelength among the at least two color forming moieties, a difference between the maximum absorption wavelength of the first color forming moiety and the maximum absorption wavelength of the second color forming moiety being from 50 nm to 400 nm, and the first color forming moiety and the second color forming moiety being bonded through a covalent bond.
