電圧対静電容量特性を用いたフレクソ係数の測定における不純物イオンの影響

抄録

A light leakage from pixel edges with the high resolution LC panel has been noticed. It is considered that a flexoelectric effect is one of causes. Evaluations of the flexo-coefficient of LC materials is required. However, the separation of impurity ions which is contained LC materials is the most difficult problem. Our group have attempted to evaluate the flexo-coefficients (e11+e33) for the pure LC materials by extrapolating the graph of the flexo-coefficients vs VHR curve. Then, 12.34 pC/m of the coefficient (e11 + e33) was estimated with no impurity ions for the nematic mixture ZLI-4792.
