The disclosure pertains to a method of switching a C-chiral smectic liquid crystal cell exhibiting a planar alignment of book-page or bookshelf geometry, the cell being aligned by partitions (2, 3). The method is characterised in that it involves at least the following sequence of operations: a first strong electrical field Ep is applied substantially parallel to the alignment partitions at an angle of between 90 and 10 degrees to the perpendicular to the plane of the smectic layers; this electrical field is shut down; an electrical field EN is applied, comprising at least one orientation component which is perpendicular to the alignment faces, the field direction being selected in accordance with the desired final ferro-electrical alignment of the smectic layer. |
