Abstract
An electrode is provided on one surface of each of a pair of substrates. On the other surface of each of the substrates, a polarizer is provided. The substrates are assembled together so that their surfaces on which the electrodes are formed face each other. Then, a medium is introduced between the substrates, to form a dielectric material layer. The medium is prepared by mixing a chiral agent in a negative type liquid crystalline compound.
