ABSTRACT:
The present invention provides particles for display media constituting the display media used for an information display panel, in which the display media are sealed between two substrates, at least one of two substrates being transparent, and, in which the display media, to which an electrostatic field is applied, are made to move so as to display information, comprising: the particles having a substantially spherical shape, which are made by polymerizing raw materials including monomers, which include (acrylic or methacrylic) resin-hydrocarbon resin copolymer in the particles, in which a part of or all of the monomers are a multifunctional monomer having a plurality of polymerization reactive groups in one molecule, and which have minute irregularities on their surface evenly. By such a construction, the particles for display media can obtain irregularities firmly fixed on their surface. Poor display can be solved by using the same.
