Abstract:
A MIM-liquid crystal display comprisinga MIM diode array, and a pair of parallel substrates having a nematic liquid crystalline medium disposed between the pair of substrates, wherein the nematic liquid crystalline medium exhibits a dielectric anisotropy of 3.0 to 4.0 and a dielectric constant perpendicular to the longitudinal molecular axes of &gE;4.2, and comprises: a) a component A comprising one or more compounds of the formula I â€ƒwherein R1 is alkyl, alkoxy, alkenyloxy, oxaalkyl or alkenyl with 1 to 15 C atoms, Q is CF2, OCF2, OCF2CF2 or a single bond, X is F or CI, Z1 is a single bond, and Z2 is â€”Câ‰¡Câ€”, â€”CH2CH2â€” or a single bond, L1, L2, L3 and L4 are each independently H or F, and m is 0 or 1, and b) a component B comprising one or more compounds of the formula II â€ƒwherein R2 has the meaning for R1, Z3 is â€”COâ€”Oâ€”, â€”CH2â€”Oâ€”, â€”Câ‰¡Câ€” or a single bond, Z4 is â€”COâ€”Oâ€”, â€”CH2Oâ€” or â€”Câ‰¡Câ€”, has the meaning given for andn is 0 or 1.
