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.
Claims9
A liquid crystal display device, comprising:
- a pair of substrates;
- liquid crystal held between said substrates;
- an electrode formed on at least one of opposite faces of said substrates;
- and
- an optical scattering layer formed on at least one of said substrates, said optical scattering layer including a resin and fine particles, said fine particles being dispersed in said resin and having different refractive indexes from that of said resin,
- said fine particles having such a dispersion in radius being contained in said resin of said optical scattering layer that light which has passed through said optical scattering layer and has been scattered has a dispersion in light tristimulus values, X value, Y value, and Z value falling within 10% at each angle in an angle range from 5° to 20° with respect to a traveling direction of incoming light.
