ABSTRACT:
A process for fabricating a polymer-dispersed liquid crystal electro-optical device, which comprises: placing a mixture of a liquid crystal material having anisotropy in refractive index and a photocurable resin on a substrate equipped with an electrode; and curing the resin by irradiating a light to said mixture; wherein, said light has such a wavelength distribution that it covers the peak of light absorption of the portion which undergoes photo-curing reaction in said photocurable resin, provided that 90% or more of said light is distributed within a wavelength range .+-.20 nm from the wavelength of said light absorption peak of the resin.
