<p>To provide a liquid crystal optical device showing a low haze value in the transparent state, further an excellent stability in the transparent-scattering characteristics and productivity, and to provide a production process thereof. The liquid crystal optical device in the embodiment 1 of the present invention is a liquid crystal optical device 1 comprising a pair of insulating substrates 11 and 21, of which at least one is transparent, electrodes 12 and 22 formed on respective inner faces of the substrates, and a composite 50 comprising nematic liquid crystal and a cured material, interposed between the inner faces of the substrates. The composite 50 is obtained by curing the following curable compound in the following chiral nematic liquid crystal composition in a state where the liquid crystal composition is interposed between the inner faces of the insulating substrates and the liquid crystal is aligned:
chiral nematic liquid crystal composition: a liquid crystal composition showing a chiral nematic phase, comprising nematic liquid crystal and a curable compound, wherein at least a part of the curable compound is an optically active material having an optical rotatory power, and the optically active material having an optical rotatory power consists substantially solely of the curable compound.</p> |
