ABSTRACT:
A liquid crystal electro-optical device is fabricated by holding a mixture of a liquid crystal material and an uncured resin between a pair of substrates, precipitating the uncured resin from the mixture in the form of columns, and curing the thus precipitated columns of uncured resin. wherein a ultraviolet-curable resin is used as the sealing material and the uncured resin to cure the both by irradiating an ultraviolet radiation thereto. In this manner, the curing of the sealing material and the resin columns can be completed in a single process. Also, in a liquid crystal electro-optical device comprising a pair of substrates in which one of them is a light-transmitting substrate, a fabricating process comprises precipitating an uncured resin from a mixture of a liquid crystal material and a resin curable by either or both of ultraviolet radiation and heating, and curing the precipitated resin by irradiating an ultraviolet radiation and heating. Furthermore, the surface state of the plane of at least one of the substrates to be in contact with the liquid crystal mixture is partially modified or rendered hydrophobic and/or hydrophilic to control the precipitation position of the resin.
