Abstract
A particle dispersion for display includes color particles for display that move in response to an electric field and include first color particles and second color particles; and a dispersion medium that disperses the color particles for display, in which the second color particles have a larger particle diameter than a particle diameter of the first color particles and the same charging characteristic as a charging characteristic of the first color particles, and in the color particles for display, a ratio (Cs/Cl) of a charge amount Cs of the first color particles per unit area of display to a charge amount Cl of the second color particles per unit area of display is less than or equal to 5.
