PURPOSE:To prevent the disturbance in the orientation of liquid crystal molecules by external force, etc., and to obtain a wide visual field angle by fixing a pair of nonflexible transparent plates to the outer sides of transparent conductive plastic substrates holding a liquid crystal material therebetween on the peripheral side of the liquid crystal element in such a manner that the polarization action surfaces exist on the inner side. CONSTITUTION:This element has a liquid crystal unit L formed by holding the liquid crystal material 1 exhibiting a smectic phase with a pair of the soft transparent conductive plastic base materials 1 and a pair of the nonflexible transparent plates 3 larger in size than this unit. After the liquid crystal unit L is held by the nonflexible transparent plates 3, the transparent plates are tightened by screw holes 3a at four corners, by which the liquid crystal unit is brought into pressurized contact therewith. The nonflexible transparent plates 3 are formed by laminating polarizing films via tacky adhesive layers on the surfaces of the plastic substrates 2. The nonflexible transparent plates 3 are brought into pressurized contact with the transparent conductive plastic base materials 2 in such a manner that the polarizing films come to the inner side. Then, the easy disturbance in the orientation of the liquid crystal molecules is prevented by the protective effect of the nonflexible transparent plates laminated on the outer side even if the external force, etc., are applied thereon. |
