摘要:
Disclosed are white particles for an image display device which includes: (i) a pair of substrates facing each other, provided that at least one of the substrates is transparent; and (ii) the white particles enclosed in a gap between the substrates, with which an image is displayed through migration of the white particles by generating an electric field between the substrates, wherein each of the white particles contains: (a) a core particles containing an inorganic oxide having a refractive index of 2.0 or more in an amount of 80 to 99 weight % based on the total weight of the core particle; and (b) a resin layer having a thickness of 10 to 1000 nm on a surface of the core particle.
