A liquid crystal device is constructed in such a structure that a plurality of stripe bulkheads substantially perpendicular to a direction of a layer of a smectic liquid crystal are provided on at least one of a pair of substrates retaining the smectic liquid crystal therebetween and that an elastic modulus E of the bulkheads, an outside pressure P, an area A1 of the substrate, a total area A2 of contact surfaces between the bulkheads and the substrate, and a volumetric shrinkage ratio DELTAVlc/Vlc of the smectic liquid crystal within an ambient temperature range of the liquid crystal device satisfy the following relation:<paragraph lvl="0"><in-line-formula>(1/E)xPx(A1/A2)>=DELTAVlc/Vlc,</in-line-formula>whereby the bulkheads become able to be compressed in response to volumetric shrinkage of the liquid crystal.
