　　The uniformly lying helix(ULH)state constitutes a class of cholesteric textures showing unidirectionally aligned helices with their axes parallel to the plane of substrates.Unlike the generation of the well-known planar(P)and the focal conic(FC)states,a specific means [1-3] is required to obtain a defect-free ULH structure in a cholesteric liquid crystal(CLC)cell.
