Patent

CA 2399958

The invention concerns a method for producing nematic liquid crystal devices, characterised in that a low zenithal anchoring energy is obtained on at least one of the confinement plates by steps which consist in: depositing on a substrate, a polyvinyl chloride polymer or copolymer; stabilising the deposition; defining an azimuthal orientation of the deposition inducing a controlled azimuthal anchorage of the liquid crystal.

La présente invention concerne un procédé réalisation de dispositifs à cristaux liquides nématiques, caractérisé par le fait qu'une faible énergie d'ancrage zénithale du cristal liquide est obtenue sur au moins une des plaques de confinement par les étapes consistant à: ~ déposer sur un substrat, un polymère ou un copolymère à base de poly(chlorure de vinyle), ~ stabiliser le dépôt, ~ définir une orientation azimutale du dépôt induisant un ancrage azimutal contrôlé du cristal liquide.
