Title (EN) LIQUID CRYSTAL COMPOSITION AND LIQUID CRYSTAL DISPLAY ELEMENT
(FR) COMPOSITION DE CRISTAUX LIQUIDES ET ÉLÉMENT D’AFFICHAGE À CRISTAUX LIQUIDES
(JA) 液晶組成物および液晶表示素子
Abstract:
(EN) Provided is a liquid crystal composition which satisfies at least one of characteristics such as a high upper limit temperature, a low lower limit temperature, a low viscosity, an appropriate optical anisotropy, a high negative dielectric anisotropy, a high specific resistance, high stability against ultraviolet light, high stability against heat, and inhibition of display defects such as afterimages, or which has an appropriate balance between at least two of these characteristics. Provided is an AM element which has characteristics such as a short response time, a large voltage holding ratio, a low threshold voltage, a large contrast ratio, and a long life. This liquid crystal composition has a compound having high solubility in the liquid crystal composition, contains, as a first additive, a compound having the effect of inhibiting display defects of a liquid crystal display element, and has a positive dielectric anisotropy. The composition may contain a specific compound having a high positive dielectric anisotropy as a first component, a specific compound having a high upper limit of temperature or a low viscosity as a second component, and a specific compound having a negative dielectric anisotropy as a third component.

La présente invention concerne également un élément (AM) qui présente des caractéristiques telles qu’un court temps de réponse, un grand rapport de maintien de tension, une tension seuil faible, un grand rapport de contraste, et une longue durée de vie. Cette composition de cristaux liquides possède un composé ayant une solubilité élevée dans la composition de cristaux liquides, contient, comme premier additif, un composé ayant l’effet d’inhiber les défauts d’affichage d’un élément d’affichage à cristaux liquides, et présente une anisotropie diélectrique positive. La composition peut contenir un composé spécifique ayant une anisotropie diélectrique positive élevée comme premier constituant, un composé spécifique ayant une limite supérieure élevée de température ou une faible viscosité comme second constituant, et un composé spécifique ayant une anisotropie diélectrique négative comme troisième constituant.
