The development and industrialization of some liquid crystal materials: the ester with strong positive dielectric anisotropy for TN LCD, the tolan with large birefringence, the alkenyl with large k33/k11 elastic ratio and the azine with large birefringence and high N-I transition temperature for STN LCD, and the fluorinated liquid crystals of fused ring systems for TFT LCD, are reviewed. The work on new fluorinated naphthalene with negative dielectric anisotropy for VA LCD is introduced.
