Title (EN) LIQUID CRYSTAL COMPOUND, LIQUID CRYSTAL COMPOSITION, THIN FILM AND LIQUID CRYSTAL DISPLAY
(FR) COMPOSÉ DE CRISTAUX LIQUIDES, COMPOSITION DE CRISTAUX LIQUIDES, PELLICULE MINCE ET AFFICHAGE À CRISTAUX LIQUIDES
Abstract: front page image
(EN)A liquid crystal compound is provided and includes a region in which an aromatic heterocyclic ring and an aromatic hydrocarbon ring linked together through a single bond, the liquid crystal compound expressing a nematic liquid crystal phase satisfying relational expression (1): 1.1 ≤ (nx - nz)/(nx - ny) ≤ 20 nx, ny and nz represent refractive indexes in three intersecting directions of the nematic liquid crystal phase, nx is the largest refractive index, and nz is the smallest refractive index.
(FR)La présente invention concerne un composé de cristaux liquides qui comprend une zone dans laquelle un anneau hétérocyclique aromatique et un anneau hydrocarbure aromatique sont reliés ensemble au moyen d’une liaison simple, le composé de cristaux liquides exprimant une phase de cristaux liquides nématique satisfaisant l’expression relationnelle (1) : 1,1 ≤ (nx - nz)/(nx - ny) ≤ 20, nx, ny et nz représentant les indices de réfraction dans les trois directions d’intersection de la phase de cristaux liquides nématique, nx étant l'indice de réfraction le plus élevé, et nz étant l'indice de réfraction le plus faible.
