Electro-optical liquid crystal display |
摘要 |
<p>An electrooptical LCD has an orientation film, the field of which has a significant component parallel to the liquid crystal (LC) layer, and an LC medium with positive dielectric anisotropy, which contains mesogenic cpd(s). with a 3,4,5-trifluorophenyl gp. (Ph.3F) and/or mesogenic cpd(s). contg. a unit of formula T<1> - Z - T<2>-CN (A); T<1> = a gp. of formula (B); and T<2> = a gp. of formula (C); A = O or CH; Z = -COO- or a single bond; L<1> = F or, if A = O, may also = H; L<2> = H or F. Also claimed is a liquid crystal medium with positive dielectric anisotropy.</p> |
