Molecular alignment for which the director rotates in a helical fashion when passing between two substrate surfaces having molecules in uniform planar alignments.

Note 1: The length of a line in Fig. indicates the length of a director projected onto the plane of the page.

Note 2: The orientation of the directors on the upper and lower substrate surfaces are usually mutually orthogonal and hence the directors undergo a 90° twist over the thickness of the liquid-crystal layer.
