Liquid crystals of the diester type, their mixture with mesomorphic compounds and display device employing this liquid cristals |
| abstract |
The invention relates to a body of diester type, that is to say an organic compound with three benzene nuclei joined by groups -COO-, having at least one mesomorphic phase of smectic type.n n n The body according to the invention corresponds to the formula: where R 1 is an alkyl or an alkoxy and R 2 an alkyl. In the case where R 1 is an octyl and R 2 a pentyl, there is a dielectric isotropy frequency of 30 kHz, that is to say a frequency where the dielectric anisotropy changes sign.n n n Application to field effect display devices with dual frequency memory. |
