Abstract
The present invention provides a liquid crystal optical device showing small haze value in transparent state and being excellent in productivity, a process for producing such a device, and a liquid crystal composition for producing such a device. The liquid crystal composition of the present invention is a liquid crystal composition containing a nematic liquid crystal and at least two types of optically active materials having different optical rotatory directions, wherein one of the optically active materials having different optical rotatory directions is a non-curable compound, the other one of the optically active materials is a curable compound, and the liquid crystal composition as a whole shows a nematic phase. By sandwiching the liquid crystal composition between inner faces of a pair of insulation substrates at least one of which is transparent, and curing the curable compound in a state that the liquid crystal is aligned, it is possible to obtain a liquid crystal optical device showing small haze value in transparent state and being excellent in productivity.
