Abstract

In planar nematic liquid crystals cells twist deformation was generated through photoalignment. By increasing the twist angle gradually, supertwisted cells were constructed in the range of 2π-3π twist angle. The supertwist relaxed through the formation of either π or 2π inversion loops, depending on the character of the photosensitive substrate. The difference in the relaxation process can be related to the zenithal anchoring strength on the photosensitive plate.
