<p>In an information display panel, (1) display medium particles constituting at least one type of display medium consist of approximately spherical particles obtained by polymerizing a monomer-containing particle raw material, the particle raw material containing a (meth)acrylic resin-hydrocarbon resin copolymer or (meth)acrylic resin-(meth)acrylic resin (having a hydrocarbon or fluorinated hydrocarbon in side chains thereof) copolymer, the monomer in part or entirety consisting of a polyfunctional monomer having multiple polymerization reaction groups in each molecule thereof, the particles at the surface thereof having uniform minute irregularities. (2) All the particles constituting display mediums have a diameter of = 500 nm.</p>
