Liquid Crystal Displays(LCDs) have been developed because of their features: low power consumption and flat plate.
They have been widely employed in enterprises, homes and open air, all the better for such features. Potable notebook type of personal computers(PC) have been expanding in proportion to a development of large scale LCD panels. Especially, TFT-LCDs have been so remarkably improved in their image quality as flat panel display that they have already been employed for monitor display in PCs.
Chemical compounds of fluorinated derivatives are the most suitable and indispensable materials for TFT-LCD. It is Chisso Corporation that firstly developed the liquid crystal materials of fluorinated derivatives and that successfully established the manufacturing methods in the world.
In this paper, we are reporting a development process and introducing the properties of fluorinated materials. Furthermore, we are reporting the subjects that are needed for LCDs' future and introducing the present developing situation.
