Abstract: PROBLEM TO BE SOLVED: To prevent the decomposition of a charge controlling agent and to suppress the generation of low-molecule components by using the charge controlling agent having a structure which is not easily decomposed as a charge controlling agent for display medium particles composing a display medium to be used for an information display panel.
SOLUTION: An electric field is applied to one sort or more of display media having optical reflectance and electrostatic chargeability sealed into a space between substrates 1, 2 and the display media are moved to display information such as an image on an information display panel. As a charge controlling agent with negative chargeability for negatively charging display medium particles composing the display medium to be used for the information display panel, a zirconium compound, preferably salicylic acid zirconium complex, is used to prevent the decomposition of the charge controlling agent and to suppress the generation of low molecule components.
