A periodical texture with two types of periodical domains is induced in a nematic liquid crystal cell under the existence of an elastic wave propagating on a glass plate. The shorter periodical domain and the Williams domain are induced in the same liquid crystal cell. The dark and bright regions are observed in the Williams domain, while two color regions are recognized in the bright region of the shorter periodical domain. The liquid crystal flows along the dark region in the shorter periodical domain, while the flow directors in the neighboring dark regions are in the antiparallel direction.
