Title (EN) CELLS AND LAYERED STRUCTURES COMPRISING POLYIMIDE ALIGNMENT LAYERS AND BASED ON LIQUID CRYSTAL SOLUTIONS OF LYOTROPIC CHROMONIC LIQUID CRYSTALS AND SURFACE ACTIVE AGENTS AND METHODS OF THEIR MANUFACTURE
(FR) CELLULES ET STRUCTURES STRATIFIÉES COMPRENANT DES COUCHES D'ALIGNEMENT EN POLYIMIDE ET BASÉES SUR DES SOLUTIONS DE CRISTAL LIQUIDE DE CRISTAUX LIQUIDES CHROMONIQUES LYOTROPIQUES ET AGENTS ACTIFS EN SURFACE ET LEURS PROCÉDÉS DE FABRICATION
Abstract:
(EN) The invention relates to liquid crystal cells and layered structures comprising polyimide alignment layers and a solution of a lyotropic chromonic liquid crystal, e.g. disodium cromoglycate (DSCG), in combination with one or more surface agents, e.g. a member of the Triton X family. The incorporation of a suitable amount of one or more surface agents, such that their concentration within the solution lies in a predetermined range, improves the homogeneity and time-stability of the alignment of liquid crystal molecules on the polyimide alignment layers.
(FR) L'invention concerne des cellules et des structures stratifiées à cristaux liquides comprenant des couches d'alignement en polyimide et une solution d'un cristal liquide chromonique lyotropique, par exemple du cromoglycate disodique (DSCG), en combinaison avec un ou plusieurs agents de surface, par exemple un membre de la famille du Triton X. L'incorporation d'une quantité appropriée d'un ou plusieurs agents de surface, de telle sorte que leur concentration dans la solution se situe dans une plage prédéterminée, améliore l'homogénéité et la stabilité temporelle de l'alignement des molécules de cristaux liquides sur les couches d'alignement en polyimide.
