A light-modulating liquid-crystal element comprising two substrates which each have an electrode layer and at least one of which is transparent, and a light-modulating layer supported between these substrates, wherein the light-modulating layer comprises a nematic liquid-crystal material and a transparent solid substance, and the nematic liquid-crystal material comprises a compound represented by the following general formula (I), and/or a compound represented by the following general formula (II), and a compound represented by the general formula (III), the nematic liquid-crystal material being dispersed as independent microdroplets in the transparent solid substance, the microdroplets having an average particle diameter of 0.1 to 50 µm.
(In the formulae, R 1 to R 3 each independently is an alkyl group having 1 to 10 carbon atoms or the like;
A 1 and A 2 each independently is trans-1,4-cyclohexylene or 1,4-phenylene;
X 1 and X 2 each independently is a cyano group, an alkyl group having 1 to 10 carbon atoms, or the like.) |
