ABSTRACT:
A liquid crystal electro-optical device based on a dispersion-type liquid crystal, comprising a pair of substrates at least one of which is light-transmitting, having established thereon electrodes and an electro-optical modulating layer having incorporated between said pair of substrates, said electro-optical modulating layer being composed of a resin support having dispersed therein a liquid crystal material, wherein, the liquid crystal material as viewed in the cross section is dispersed in the resin support as droplets flattened along the direction parallel to the substrates. The dispersion-type liquid crystal electro-optical device according to the present invention has a high scattering efficiency and provides an excellent light-transmittance upon application of an electric field.
