    摘要： The invention relates to a liquid-crystalline medium, preferably having a nematic phase and dielectric anisotropy of 0.5 or more, which comprises one or more compounds of formula T

    in which

    denotes

    and the other parameters have the meanings given in the text,
    to the use thereof in an electro-optical display, particularly in an active-matrix display based on the IPS or FFS effect, to displays of this type which contain a liquid-crystalline medium of this type, and to the compounds of formula T and their use for the improvement of the transmission and/or response times of a liquid-crystalline medium which comprises one or more additional mesogenic compounds.

    摘要： Verbindungen der Formel I,

    worin Y 1 -O- oder -CH 2 - bedeutet, und die Gruppen R 1 , L 1 bis L 6 und X 1 die in Anspruch 1 angegebenen Bedeutungen haben. Ein Verfahren zu ihrer Herstellung, sowie flüssigkristalline Medien enthaltend mindestens eine Verbindung der Formel I und elektrooptische Anzeigen enthaltend ein solches flüssigkristallines Medium. Die Verbindungen der Formel I umfassen als Strukturelement eine Kombination aus einem 1,4-substituierten Cyclohexenring neben einem Dioxan- oder Tetrahydropyranring und einer substituierten Biphenylgruppe.

    摘要： The present invention relates to compounds of formula I

    in which the occurring groups have the meanings defined in claim 1 and A 13 denotes certain heterocyclic ring groups including benzothiadiazols, to liquid crystal media comprising the compounds, and to high-frequency components comprising these media, especially microwave components for high-frequency devices, such as devices for shifting the phase of microwaves, tunable filters, tunable metamaterial structures, and electronic beam steering antennas (e.g. phased array antennas), and to devices comprising said components. The invention further relates to an optical component comprising said liquid-crystalline media, operable in the infrared region of the electromagnetic spectrum.
