Abstract: PROBLEM TO BE SOLVED: To provide a dimming liquid crystal device having sufficient contrast, drivable over a wide temperature range, and excellent in light resistance(weatherability) in particular. SOLUTION: The dimming liquid crystal device comprises two base plates having electrode layers with at least one of the base plates being transparent, and a dimming layer supported in between these base plates. In this device, the dimming layer comprises a nematic liquid crystal material and a transparent solid material, wherein the nematic liquid crystal material comprises a compound of the general formula(I) and/or a compound of the general formula(II) and a compound of the general formula(III) and is dispersed in the transparent solid material in the form of independent microdroplets whose average size is 0.1-50μm. In the general formulas(I), (II) and (III), R 1 to R 3 are each independently a 1-10C alkyl or the like; A 1 and A 2 are each independently a trans-1,4-cyclohexylene or 1,4-phenylene group; x 1 and x 2 are each independently cyano, a 1-10C alkyl or the like.
