Abstract
Most electrooptic effects in liquid crystals require a uniform orienta tion of the director at the glass substrates. A new method to produce suitable alignment layers is based on the creation of anisotropic poly mer films by photopolymerization with linearly polarized light. In the present paper we report on measurements of the anchoring strength of these photo-induced anisotropic films. Using a wedge-cell technique, w e find an azimuthal anchoring energy of W(phi)approximate to 2.3 . 10( -6) J/m(2).
