Abstract The ion adsorption on an aligning layer deposited onto a conductive electrode in a liquid crystal cell has been shown to depend strongly on the dielectric constants of the layer and its thickness d. Calculations made in the framework of the three‐layer electrostatic theory showed that, depending on those and other intrinsic parameter of the problems, it is possible to observe either ion attraction or repulsion at the aligning surface. Tentative measurements of the ion adsorption dynamics on the aligning layers with various d qualitatively agree with the theory. The results obtained allow the memory effect in liquid crystals and the sticking effect in liquid crystal displays to be controlled effectively.
