DEVELOPMENT OF NEW LIQUID-CRYSTAL MATERIALS FOR TFT LCDS

We report recent progress in the development of Liquid Crystal (LC) ma terials for the TN-TFT and ECB-TFT technologies, which require LC mate rials with positive and negative dielectric anisotropy, respectively. Many kinds of new LC materials have been synthesized and have been eva luated based on their fundamental physical properties. We have succeed ed in identifying new LC materials, and developing new LC mixtures bas ed on those, so that the current typical requirements of TFT-LCDs e.g. fast switching times, low power consumption, good viewing angles and wide operation temperature ranges together with high reliability can b e fulfilled.
