Abstract: The observation of smectic schlieren textures with singularities of high stgrength in the sample is reported.The sample is Schiff-Base type liquild crystal with ortho-hydroxy, 4-undecenoyloxy resorcylidene-4′-decyloxyaniline.The highest strength of these singularity points is —8,the singularity points with S=—6,—4,—3,—2 are also observed,and their stability is good.The forming process of the singularity points with high strength is also observed,the center of the disclination points is an isotropic area.

Key words: High strength disclination points, Smectic schlieren texture, Liquild crystal
