| 摘要 |
A liquid-crystal display device having a twisted nematic liquid-crystalline material is provided with a layer of an optically anisotropic material to obtain a colourless display device which is rich in contrast. The optically anisotropic material exhibits a substantial temperature dependence and a high degree of molecular order as a result of the fact that it is formed from a synthetic resin composition comprising a polymer network having a helicoidal order. The optically anisotropic material is manufactured from a liquid-crystalline curable synthetic resin composition having a chiral dopant. |
