Blending of Novel Liquid Crystal Mixtures for TFT-LCD TV Application

Tree-ring types liquid crystalline compounds having fluoro and isothiocyanate substituent[1] were synthesized and their physical properties were measured to evaluate the applications to TFT-LCD TV. All synthesized compounds were showed remarkably high Tni point. Birefringence(${\triangle}n$) and dielectric anisotropy(${\triangle}{\varepsilon}$) were higher than fluoro analogues and isothiocyanate substituted bicyclohexyl-phenyl compounds.
