ABSTRACT:
A liquid crystal optical device comprising a pair of substrates provided with electrodes and a layer containing a liquid crystal material sandwiched between the pair of substrates, wherein said layer is formed by irradiating light to a solution of a nematic liquid crystal material and a photo-curable vinyl compound selected so that the refractive index of the resulting cured product agrees to either the ordinary refractive index (n.sub.o) or the extraordinary refractive index (n.sub.e) of the nematic liquid crystal material used, or the refractive index (n.sub.x) of the nematic liquid crystal material when it is randomly oriented, held between the pair of substrates provided with electrodes, to cure the photo-curable vinyl compound and fix the resulting phase separation of the nematic liquid crystal material and the cured product.
