Title (EN) LYOTROPIC MESOMORPHIC MEDIA AND OPTICAL COMPENSATING FILM USING THE SAME
(FR) MILIEUX LYOTROPIQUES ET MESOMORPHES ET FILM DE COMPENSATION OPTIQUE DANS LEQUEL LESDITS MILIEUX SONT UTILISES
Abstract:
(EN) Lyotropic mesomorphic namatic or columnar media consisting of sheet-like molecules and non-polar solvents (e.g. alkanes, decahydronaphthalene and other hydrocarbons), having negative optical birefringence, for the construction of optical compensators for liquid crystal displays, is provided. The sheet-like molecules can be low molecular weight molecules, or polymers with sheet-like side groups, or polymerizable monomers resulting in polymers with sheet-like units, and represented by formulas (1-1), (1-30), etc., for example. In said formulas, R is an alkyl or alkoxy group in which methylene moiety may be replaced by O, S, COO, OCO, CH=CH or C$m(Z)C.
(FR) L'invention concerne des milieux lyotropiques et mésomorphes du type namatique ou colonnaire constitués de molécules du type feuille et de solvants non polaires (ex, alcanes, décahydronaphtalène et autres hydrocarbures), présentant une biréfringence optique négative, pour la construction de compensateurs optiques pour afficheurs à cristaux liquides. Les molécules du type feuille peuvent être des molécules de faible poids molaire, ou des polymères à groupes latéraux du type feuille, ou des monomères polymérisables qui donnent des polymères à motifs en feuille, et sont représentées par les formules (1-1), (1-30), etc. Dans lesdites formules, R est un groupe alkyle ou alcoxy dans lequel le fragment méthylène peut être remplacé par O, S, COO, OCO, CH=CH ou C$m(Z)C.
