Abstract:
A liquid crystal device comprising a pair of substrates retaining a smectic liquid crystal therebetween and a plurality of bulkheads intersecting with a direction of a layer of the smectic liquid crystal provided on at least one of the pair of substrates,wherein 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 &Dgr;Vlc/Vlc of the smectic liquid crystal within a temperature variation range of an atmosphere in which the liquid crystal device is placed satisfy the following relation: (1/E)Ã—PÃ—(A1/A2)&gE;&Dgr;Vlc/Vlc.
