PROBLEM TO BE SOLVED: To provide particles for display media from which a panel for information display having excellent display quality can be obtained when the display mediums constituted of the particles for the display media are used by setting charge holding ratios of two kinds of particles for the display media which constitute two kinds of display media in suitable ranges. SOLUTION: The panel for information display displays information such as an image by encapsulating at least two kinds of display media having optical reflectance values and charge characteristics different from each other in a space between two substrates 1 and 2 and applying an electric field to the display media to transfer the display media. Relating to the particles for the display media which constitute the display media used for the panel for information display, one of a charge holding ratio R<SB>25</SB>1 at 25°C for 300 hours of particles 1 for the display media and a charge holding ratio R<SB>25</SB>2 at 25°C for 300 hours of particles 2 for the display media is set to≥90% and the other is set to <90%. Thereby, the panel for information display using the two kinds of display media constituted of the two kinds of particles for the display media and having excellent display quality is provided.
