FERROELECTRIC LIQUID CRYSTAL DEVICES |
摘要 |
Ferroelectric liquid crystal devices are described which contain liquid crystal mixtures comprising components A and B. Component A consists of one or more optically active compounds capable of imparting a spontaneous polarisation to the material. Component B is selected as one or more compounds having formula (I), wherein a, b and c are independently 0, 1, 2; R1 and R2 are C1-15 straight or branched chain alkyl or alkoxy, preferably C3-C12. In the above (for component B) CH=CH linking groups may be replaced by C2H4 and CH2O linking groups may be replaced by OCH2. |
