摘要：
The present invention relates to a liquid crystalline mixture comprising a) 1-25% by weight of at least one compound of the formula I b) 5-80% by weight of at least one compound of the formula II c) and optionally 1-20% by weight of at least one chiral compound with a HTP of ≦20 μm, wherein R11, A11, Z11, A12, Z12, L11, L12, L13, L14, Z13, A13, Z14, A14, X11, a, b, c, d, R12, A1, Z1, A2, Z2, A3, L1, L2, X12, m and n have the meanings given in claim 1 and their use in TFT, TN, IPS applications and expecially for devices utilizing electro-optical effects in an optically isotropic state.
