Provided are a particle dispersion for display which gives white displays having a high reflectance and in which the white particles for display are inhibited from sedimenting and an image display device equipped with the particle dispersion. The particle dispersion for display comprises: white particles for display which comprise a white pigment and a resin, have a white pigment content of 30-90 mass% and a volume-average particle diameter of 100-500 nm, and satisfy relationship (1): 400>=6kT/(pid3(rhop-rhos)g)>=30; colored particles for display which are of two or more kinds other than white and which move in accordance with an electric field; and a dispersion medium. In relationship (1), k indicates the Boltzmann constant, T indicates the absolute temperature, 298 (K), d indicates the volume-average particle diameter of the white particles for display, rhop indicates the specific gravity of the white particles for display, rhos indicates the specific gravity of the dispersion medium, and g indicates the gravitational acceleration. |
