Patent ID: 8248685

Claim:
Display particles for an image display apparatus provided with 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 have metal oxide layers formed on the entire surfaces of base particles containing at least a resin and a colorant, and the metal oxide layers comprise a polycondensation product formed by using a compound A represented by the following formula (A) and a compound B represented by the following formula (B) as materials: M 1 (OR 1 ) 4 (A) wherein M 1 represents a silicon atom or a titanium atom; and R 1 represent an alkyl group having 1 to 4 carbon atoms respectively independently: M 2 (R 2 ) 4-n (OR 3 ) n (B) wherein M 2 represents a silicon atom or a titanium atom; R 2 represent an alkyl group having 1 to 4 carbon atoms, a phenyl group, an acryloyloxy group, a methacryloyloxy group or an epoxy group independently; R 3 represent an alkyl group having 1 to 4 carbon atoms independently; and n represents an integer of 2 or 3.
