Structure of a hybrid aligned cholesteric liquid crystal cell

I. Dozov , I. Penchev

The structure of a hybrid aligned cholesteric liquid crystal sample is investigated both experimentally and theoretically. At small thickness the cell presents a structure characterized by unidimensional deformation - uniform (in the xy plane) structure. This structure is described theoretically and numerical results are presented and discussed. At large thickness there appears a more complex three dimensional deformation characterized by a domain structure due to a modulation of the director field in the xy plane. A simple idea about the type of the deformation involved in this structure is proposed and qualitatively discussed.
