摘要:
There are provided particles for display media capable of properly controlling change in an amount of charge by heating and an information display panel, by using the particles for display media capable of eliminating a display failure and reduction in contrast ratio. The present invention are particles for display media used for an information display panel, in which at least one kind of display media constituted as a group of particles including chargeable particles are sealed between two opposed substrates, at least one of two substrates being transparent, and in which the display media are made to move so as to display information, wherein two or more kinds of charge control agents (CCA) are contained in at least one kind of particles for display media, at least one kind of charge control agent is positively chargeable and at least one kind of charge control agent is negatively chargeable, the positively chargeable charge control agent is a salt comprising a compound containing a quaternary ammonium cation group and an anion and the negatively chargeable charge control agent is a salt comprising a complex anion comprising a salicylic acid derivative and a metal atom, and a cation.
