Abstract[English]
The present invention relates to liquid-crystalline (LC) media having positive dielectric anisotropy and to liquid-crystal displays (LCDs) containing these media, especially to displays addressed by an active matrix and in particular to energy efficient LC displays of the TN, PS-TN, STN, TN-TFT, OCB, IPS, PS-IPS, FFS, HB-FFS, XB-FFS, PS-FFS, SA-HB-FFS, SA-XB-FFS, polymer stabilised SA-HB-FFS, polymer stabilised SA-XB-FFS, positive VA or positive PS-VA type. The media have an improved long-term stability against UV radiation and elevated temperatures.[French]
La présente invention concerne des supports à cristaux liquides (LC) présentant une anisotropie diélectrique positive et des écrans à cristaux liquides (LCD) contenant ces supports, notamment des écrans adressés par une matrice active et plus particulièrement des écrans LC à haut rendement énergétique du type TN, PS-TN, STN, TN-TFT, OCB, IPS, PS-IPS, FFS, HB-FFS, XB-FFS, PS-FFS, SA-HB-FFS, SA-XB-FFS, SA-HB-FFS stabilisé par polymère, SA-XB-FFS stabilisé par polymère, de type VA positif ou PS-VA positif. Les milieux présentent une meilleure stabilité à long terme contre les rayons UV et les températures élevées.
