Particle dispersion for display, display medium, and display device
First Claim
1. A particle dispersion for display comprising:
- 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,wherein the second color particles have a larger particle diameter than a particle diameter of the first color particles,wherein in the color particles for display, a ratio (Cs/C1) 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, andwherein the first color particles and the second color particles are positively charged, or the first color particles and the second color particles are negatively charged.

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.
