Abstract
Die vorliegende Erfindung betrifft ein elektrooptisches Lichtsteuerelement vom FFS-Typ, sowie elektrooptische Anzeigen und Anzeigesysteme wie z. B. Fernsehbildschirme und Computermonitore, die solche Elemente enthalten. Die erfindungsgemäßen Lichtsteuerelemente enthalten ein flüssigkristallines Steuermedium, das optimierte elastische Konstanten aufweist, und sind neben einem guten Kontrast, einer geringen Blickwinkelabhängigkeit, kurzen Schaltzeiten und geringe Ansteuerspannungen besonders durch einen hohen Kontrast bzw. optimierte Transmission ausgezeichnet. Die in den elektrooptischen Lichtsteuerelementen verwendeten flüssigkristallinen Steuermedien sind ebenfalls Gegenstand der vorliegenden Erfindung.
