Abstract

L'invention concerne des procédés destinés à concevoir des ensembles rigides ou flexibles de dispositifs électro-optiques, notamment grâce à une technique d'élaboration de structures composites à phases séparées qui permet d'obtenir des zones adjacentes de polymères et de cristaux liquides (LC) selon une architecture spécifique, et non une dispersion aléatoire des gouttelettes de LC. On peut préparer les dispositifs susmentionnés en produisant des volumes d'une structure de LC (56) à proximité d'une zone polymère (58), par une séparation de phase anisotropique des LC à partir d'un photopolymère, cette séparation étant initiée par une exposition au rayonnement ultraviolet. On peut donc déterminer facilement la forme, la taille, et la disposition de ces zones dans une cellule à l'aide d'un masque optique ou d'un faisceau laser. On peut par ailleurs fixer les limites du volume de LC en ajustant la composition chimique du polymère et en utilisant une couche d'alignement (28).
