abstract |
The present invention relates to a liquid-crystalline phase having at least two liquid crystalline components, wherein at least one component represents a heterocyclic compound of the formula I R1A1Z1A2 & Z2A3! NR2. Obvious known technical solutions are described in JP 60-149 564-A, JP 60-163 865-A and JP 60-199 882-A. The invention is used in the manufacture of electro-optical display elements based on liquid-crystalline dielectrics. The technical effect in the application of the invention is due to high multiplex rates, broad work areas and advantageous elastic properties in the preparation of liquid crystalline phases containing heterocyclic compounds of the formula I. |
