Long Pitch Super Twisted Nematic（LPSTN）構造が安定化するカイラルピッチとセル厚の関係

抄録

We succeeded in the stabilization of Long Pitch Super Twisted Nematic (LPSTN), which has a relationship d/p (d: cell thickness, p: chiral pitch) > 2.7 by using polymer stabilization with an applied voltage near the clearing temperature. LPSTN structure is a regular STN without an applied voltage while it changes to reversed twisted nematic (RTN) over Fredericks voltage. We are going to introduce a stabilization condition of LPSTN and RTN structures with experimental and simulation data for various d/p values.
