Abstract: An object of the present invention is to provide a dispersion type liquid crystal electro-optical device comprising liquid crystal droplets of uniform size without impairing the scattering properties. The present invention realizes a liquid crystal electro-optical device having excellent scattering properties which is achieved by increasing or decreasing the fraction of the organic constituent of the light-transmitting resin material without changing the amount of the liquid crystal and the number and density of the liquid crystal droplets so that the light scattering properties of the device may not be impaired, and thereby controlling the precipitation temperature of the liquid crystal droplets from the mixture to the vicinity of a temperature convenient in the fabrication, so that the solidification temperature of the resin material can be set at the vicinity of that temperature.

Abstract: A method is disclosed for making a liquid crystal composite in which droplets of a liquid crystal material are dispersed in a polymer matrix. At least one further material separates the liquid crystal material from the polymer matrix. This construction permits the polymer matrix to be selected on the basis of its environmental properties and the further material to be selected on the basis of its orientational interactions with liquid crystal material. Light valves made from such a composite exhibit improved electro-optical properties.

Abstract: To uniform the liquid crystal particle of the liquid crystal layer of a PDLCD where a liquid crystal is scattered and emulsified with a polymer, the polymer is scattered on a conductive layer of a substrate. The liquid crystal is scattered thereon to be emulsified during a predetermined hour. Thereafter, by the same method as that of forming the polymer layer, the polymer is scattered on the liquid crystal layer to form a second polymer layer thereby obtaining the homogeneous thickness of the liquid crystal layer of the PDLCD.
