| titleOfInvention | Composition for liquid crystal color display |
| abstract | PURPOSE: To provide the titled composition having a high dichroism ratio and showing high contrast by voltage application non-application, by dissolving a specific anthraquinone dye in a nematic liquid crystal with positive dielectric anisotropy. n CONSTITUTION: 1-5,Dihydroxy-4,8-dinitroanthraquinone and an alkoxybenzene are reacted at a low temp and the reaction product is reduce to obtain an anthraquinon dye shown by the formula (wherein R is alkyl). Subsequently, to a nematic liquid crystal with positive dielectric anisotropy such as a cyano-biphenyl type, a cyclohexane type or the like, the aforementioned anthraquinone dye is added in an amount of 0.01W5wt% and dissolved therein. n EFFECT: Said dye shows sufficient compatibility with the liquid crystal, has sufficient coloring capacity in a small amount, is excellent in durability and stability, does not damage an apparatus even if used for a long period of time and used in a display apparatus of a type wherein, when said composition is charged therein, a blue color of an electrode part is extinguished by application of an electric field. n COPYRIGHT: (C)1982,JPO&Japio |
