| Abstract: | The naphthalene derivative with advanced optical and electrical properties has become an extensively studied area of liquid crystalline material for display in recent years. In this paper, the advantages of these compounds are summarized, showing that naphthalene derivative is useful for preparing a liquid crystal composition with a wide temperature range of nematic phase, very large dielectric anisotropy and a small birefringence, thereby being driven at a low voltage, and suitable for high performance STN and TFT devices. |

| Keywords: | naphthalene derivative liquid crystal nematic phase threshold voltage birefringence dielectric anisotropy |
