摘要：
A liquid-crystalline mediums which contain one or more compounds of the formula A and at least one compound of the formula B wherein compounds of formula A contain at least one ring selected from and in which Ra, Rb, ring A and ring B, Y, Z1, Z2, a, L1, L2, L3, L4, L5, L6, L7, L8 and L9 are as defined herein, are suitable for use in twisted nematic (TN) and supertwisted nematic (STN) liquid-crystal displays. Such displays have very short response times and good steepnesses and angle dependencies.
