Zusammenfassung:PROBLEM TO BE SOLVED: To provide a manufacturing method of particles for display media, which manufactures charge injection type particles for maintaining initial display characteristics for a longer period. SOLUTION: In the manufacturing method of charge injection type particles for display media, for use in a panel for information display which has at least one kind of display media comprising particles enclosed in a space between two substrates, at least one of which is transparent, and has the display media moved by application of an electric field to the display media to display information like an image, a dispersion of fine metal oxide particles is prepared by hydrolysis and polycondensation in the sol-gel method, and the prepared dispersion and mother particles are mixed and agitated to adsorb fine metal oxide particles to surfaces of mother particles.
