説明

<jats:p>Generation of residual direct current (DC) voltage (VrDC) induces a serious image sticking of liquid crystal (LC) displays. VrDC is generated with the ions in a LC layer adsorbing to a surface of an alignment layer under application of DC offset voltage. We clarified the adsorption and desorption of the ions to and from the surface of the alignment layer with a kinetic model proposed by us. The analysis with using the kinetic model made clear that the processes of the adsorption and desorption occur due to the thermal fluctuation followed by the Boltzmann distribution. The ions adsorb to the surface of the alignment layer by a weak binding, such as the van der Waals interaction.</jats:p>
