ABSTRACT:
Display particles for an image display apparatus, wherein the image display apparatus comprises two substrates at least one of which is transparent, with the display particles being sealed between the substrates in a powder state, so that by generating an electric field between the substrates, the display particles are moved to display an image, wherein the display particles are formed through processes in which at least a binder resin and a colorant are kneaded and pulverized to give core particles, resin fine particles are fixed and fused on surfaces of the core particles, and then the core particles on which the resin fine particles are fixed and fused are sphered to give an average degree of roundness of 0.960 or more, and wherein a ratio of use of the resin fine particles is set in the range from 100 to 300% in the rate of the total projection area of the resin fine particles relative to the total surface area of the core particles, as well as an image display apparatus loaded with the display particles.
