The influence of ionic impurities on the Voltage Holding Ratio and Residual DC Voltage in LC cells

抄録

These experiments are performed according to the different LC's resistivities to investigate the influence of ionic impurities on the VHR and residual DC voltage using various LC cells which have different polar PI and ITO surface. We found that the increment of VHR depends on the polarity of PIs because the ionic adsorption is related to the polarity of surface, and the residual DC voltage depends mainly on the total ionic quantities rather than the polarity of PIs. In addition, we have known the different tendency of relationship between VHR and residual DC voltage depending on the pairs of LC-PI's.
