Abstract:
1. Particles for display media constituting the display media used for an information display panel, in which the display media having optical reflectance and charge characteristics are sealed between two substrates, at least one substrate being transparent, and, in which the display media, to which an electrostatic field is applied, are made to move so as to display information such as an image, comprising the particles for display media having a substantially circular shape produced by a suspension polymerization of particle materials including monomer, wherein a part of the monomer is a cross-linking monomer and an amount of the cross-linking monomer is not less than 10 parts by weight and less than 50 parts by weight, wherein a glass transition temperature Tg of the resin constituting the particles for display media is not less than 60° C.
