Patent ID: 7952794

Claim:
An image display apparatus comprising: two substrates at least one of which is transparent; and display particles that are 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, of contact surfaces with the display particles in a gap between the substrates, both of the surfaces on the substrate sides have oxide layers of the same metal, and the display particles include positively chargeable display particles and negatively chargeable display particles, both of the positively chargeable display particles and the negatively chargeable display particles have structures obtained by successively forming oxide layers of the same metal as that of the metal oxide layers possessed by the surfaces on the substrate sides and organic layers on the surfaces of base particles that contain at least a resin and a colorant, and a mixing ratio between the positively chargeable display particles and the negatively chargeable display particles is 1/3 to 3/1 in weight ratio.
