    摘要: The invention relates to supertwist liquid-crystal displays (SLCDs) having very short response times and good steepnesses and angular dependences and to the novel nematic liquid-crystal mixtures employed therein, which are distinguished by the fact that they comprise at least one compound of the formula IA and at least one compound of the formula IB and/or at least one compound of the formula IC in which Ra, Rb, Rc, Rd, Re, Y1, Y2, Y3, Y4, q and p are as defined above.

    摘要: The invention relates to TN and STN displays having very short switching times and good steepness and angular dependence and to the novel nematic liquid crystal mixtures employed therein, which are distinguished by comprising at least one compound of formula IA, where R3 is an alkenyl group having from 2 to 7 C atoms, and comprising at least one compound of formula IB, where R1 and R2 each, independently of one another, are an alkyl, alkoxy or alkenyl group having from 1 to 12 C atoms, with the additional option of 1 or 2 non-adjacent CH2 groups being replaced by —O—, —CH═CH—, —CO—, —OCO— or —COO— in such a way that O atoms are not linked directly to one another, and L is H or F.
