Residual DC voltage is one of the most important items which govern the image quality of LCD, because the existence of it causes image sticking phenomenon. However, we do not have established evaluation parameters. The generation mechanism of the residual DC voltage was analyzed based on a model of adsorption and desorption of electric charges, ions, at the interface between LC phase and alignment layer. New parameters are proposed for unified evaluation of LC and alignment materials.
