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, R1 to R3 each independently is an alkyl group having 1 to 10 carbon atoms or the like;
A1 and A2 each independently is trans-1,4-cyclohexylene or 1,4-phenylene;
X1 and X2 each independently is a cyano group, an alkyl group having 1 to 10 carbon atoms, or the like.)
