Abstract: As a dispersion in radius of fine particles contained in the resin is inappropriate, a liquid crystal display device exhibits coloring which varies with angles at which the liquid crystal display device is viewed. By selecting fine particles having such a dispersion in radius that a dispersion in light tristimulus values, X value, Y value, and Z value falls within 10% at each angle in the angle range from 5° to 20° with respect to the traveling direction of light coming into an optical scattering layer, an optical scattering layer from which the same color can be viewed even when a viewer views from different angles is prepared. The optical scattering layer can be a color filter.
