要約
(EN)
Provided is a TN liquid crystal element which is stable as a TN liquid crystal, and which has a fast response speed when being switched off. Also provided is a method for producing said TN liquid crystal element. The TN liquid crystal element is provided with: a pair of substrates, at least one of which is transparent, and which are arranged approximately in parallel; a pair of alignment films, the surface of which is subjected to alignment processing so that the liquid crystal molecules within a liquid crystal material would face the same direction, and which are disposed on the opposing surface in relation to the pair of substrates; and a liquid crystal layer which is disposed between the pair of alignment films, and which contains a liquid crystal material and a chiral agent. An angle (α) formed by the alignment processing direction of the pair of alignment films is 70° to 110°, and said alignment processing direction is a direction which forms a uniformed twist structure when the liquid crystal layer is twisted as much as the abovementioned angle (α). Moreover, an STN liquid crystal having a stable torsion angle of α+180 (°) in an electroless state is polymer-stabilized as a TN liquid crystal having a torsion angle of α (°).

L'invention concerne un élément à cristaux liquides TN qui est stable en termes de cristal liquide TN, et qui possède une vitesse de réponse rapide lorsqu'il est mis à l'arrêt. L'invention concerne également un procédé de production dudit élément à cristaux liquides TN. L'élément à cristaux liquides TN comprend : deux substrats, dont l'un au moins est transparent et qui sont disposés approximativement en parallèle ; deux films d'alignement dont la surface est soumise à un traitement d'alignement de sorte que les molécules de cristaux liquides dans un matériau de cristaux liquides soient orientées dans une même direction, et qui sont disposés sur la surface opposée par rapport aux deux substrats ; et une couche de cristaux liquides qui est disposée entre les deux films d'alignement et qui contient un matériau de cristaux liquides et un agent chiral. Un angle (α) défini par la direction de traitement d'alignement des deux films d'alignement varie de 70° à 110°, et ladite direction de traitement d'alignement est une direction qui définit une structure de torsion uniformisée lorsque la couche de cristaux liquides est tordue selon l'angle (α) susmentionné. De plus, un cristal liquide STN ayant un angle de torsion stable de α+180 (°) à l'état non alimenté est stabilisé par polymère en tant que cristal liquide ayant un angle de torsion de α (°).
