UV光照射時の印加電圧の違いによるLong Pitch Super Twisted Nematic（LPSTN）構造の安定化条件

抄録

Long Pitch Super Twisted Nematic (LPSTN) has been stabilized which has a relationship d/p (d: cell thickness divided by chiral pitch) > 2.7 by polymer stabilization with an applied voltage near the clearing temperature. The LPSTN structure is a regular STN without voltage while it changes to reversed twisted nematic (RTN) over Fredericks voltage. We are going to report a stabilization condition of LPSTN and RTN structures depending on the pretilt angle and applied voltage with simulation data of Gibbs’ Free Energy.
