Title (EN) LIQUID CRYSTAL DISPLAY ELEMENT
(FR) ÉLÉMENT D'AFFICHAGE À CRISTAUX LIQUIDES
(JA) 液晶表示素子
Abstract:
(EN) As a result of having a composition that contains one or more compounds represented by general formula (i) and one or more compounds represented by general formula (ii), the present invention provides a liquid crystal composition that is suitable for liquid crystal display elements, that does not worsen display element burn-in characteristics or liquid crystal display element characteristics such as dielectric anisotropy, viscosity, nematic phase upper limit temperature, nematic phase stability at low temperatures, and γ1, that is unlikely to result in drip marks at the time of production, and that achieves a stable discharge rate of a liquid crystal material during an ODF step. The present invention also provides a liquid crystal display element using the liquid crystal composition.
(FR) Grâce au fait de présenter une composition qui contient un ou plusieurs composés représentés par la formule générale (i) et un ou plusieurs composés représentés par la formule générale (ii), la présente invention permet d'obtenir une composition de cristaux liquides qui est appropriée pour des éléments d'affichage à cristaux liquides, qui ne dégrade pas les caractéristiques de déverminage des éléments d'affichage ou les caractéristiques des éléments d'affichage à cristaux liquides, telles que l'anisotropie diélectrique, la viscosité, la température limite supérieure de phase nématique, la stabilité de phase nématique aux basses températures et γ1, qui est peu susceptible de conduire à des marques de gouttes au moment de la production et qui permet d'obtenir un taux de décharge stable d'un matériau à cristaux liquides pendant une étape d'ODF. La présente invention concerne également un dispositif d’affichage à cristaux liquides utilisant la composition de cristaux liquides.
(JA) 一般式(i)で表される化合物を1種又は2種以上を含有し、一般式(ii)で表される化合物を1種又は2種以上を含有する組成物とすることにより、誘電率異方性、粘度、ネマチック相上限温度、低温でのネマチック相安定性、γ1等の液晶表示素子としての諸特性及び表示素子の焼き付き特性を悪化させること無く、製造時の滴下痕が発生し難く、ODF工程における安定した液晶材料の吐出量を実現する液晶表示素子に適する液晶組成物及びそれを用いた液晶表示素子を提供する。
