Abstract
A magnetic display has two non-magnetic substrates, at least one of which is transparent; and a microcapsule coating layer is applied between the non-magnetic substrates. The microcapsules contain and seal light-absorptive black magnetic fine particles and light-reflective non-magnetic fine particles dispersed in an oily dispersion liquid. An array layer is buried in a capsule wall of each of the microcapsules for enclosing the oily dispersion liquid that contains the light-absorptive black magnetic fine particles and light-reflective non-magnetic fine particles. The array layer includes flake-shaped particles with a multi-layered structure for converting the black color of a character or image formed on a display surface, which is a color inherently exhibited by the light-absorptive black magnetic fine particles, into a variety of interference colors. The flake-shaped particles are arranged so as to be oriented parallel to the surface of the capsule wall along the entire spherical surface of the microcapsule.
