An elastic wave with a glass plate as a propagation medium is investigated in relations to acoustic effects of nematic liquid crystals. The elastic wave propagating in the glass plate interacts with the liquid crystal in a wide frequency range. Two types of periodical domain structures are observed in homogeneous aligned cell of nematic liquid crystal under existence of the elastic wave. One of the periodical domain structures depends on the carrier frequency of the elastic wave. The other type of periodical domain structures is influenced by the layer thickness and kind of the liquid crystal compound. The diffraction is observed by the periodical domain structure. This diffraction is controllable for voltage application of the liquid crystal.
