| Research Abstract |
Liquid crystals are intermediate states between liquid and crystals. Nematic liquid crystal, one of liquid crystal phases, is an anisotropic fluid composed of rod-like molecules and is widely used in television and computer displays. There are many other liquid crystal phases and some of them have self-organized periodic structures of a few hundred nanometer periodicity. These phases have different opt-electric properties compared with the nematic phase and new types of liquid crystal displays using these phases are expected. In this study, we analyzed the detailed structures and emergence mechanisms of some nano-structured liquid crystalline phases. And we studied the interaction between liquid crystalline molecules and surfaces, which plays an important role on the control of the orientation structure of liquid crystals. Upon them, we made structure control of these phases by means of confinement of them inside micro-spaces.
