SUPERTWIST LIQUID-CRYSTAL DISPLAY

摘要

The invention relates to improved STN displays of which the nematic liquid crystalline medium comprises compounds of formulae: (I1, I2, II1 and/or III1). In formulae (I1 and I2) R<3> and R<4> are each independently alkyl with 1 to 8 C atoms. In formula (II1) R<1> is alkyl or alkoxy with 1 to 8 C atoms, and in formula (III1) R<2> is oxaalkyl, alkenyl with up to 8 C atoms.
