変位電流測定法の液晶セル電気光学特性解析への適用

抄録

An interpretation of the displacement current against triangular wave voltage applied to an LC cell is proposed. Constant current against voltage curve corresponds to the charging and discharging current of an LC cell capacity. Linear current against voltage curve corresponds to the ionic conductive current originated in ionic impurities in an LC cell. And nonlinear current which showed diffusion-controlling property is interpreted as the oxidation-reduction current of specific ionic impurities. By applying this method to asymmetric LC cells, we can understand the origin of image printing.
