Abstract
In this paper, an analysis of two dimensional smectic layer structure is presented to clarify the layer distortion between two chevrons directed towards opposite directions. From numerical computations, it is found that a parallelogram region appears between two antiparallel chevrons for a sufficiently large molecular tilt and thick sample. The elastic free energy density is found to concentrate near the boundaries of the kinks of the layer structure. In addition the field effect on such a pair of chevrons is presented to show that it is efficient to apply an electric field so as to obtain a quasi-bookshelf structure.
