Abstract
Models for ion behavior is given for the voltage holding ratio and residual DC voltage which cause image sticking. From the comparison of model and experiments, conductivity of LC layer, product of the number of ions, charge and mobility, was found to have correlation with voltage holding ratio. Whereas, residual DC can be described with the total charge of the adsorbed ion. In this experiments, this absorbed ion had linear correlation with the total number of ion in LC layer, and then the residual DC had the correlation with total charge of ion in LC layer.
