Abstract
Understanding the dominant factor and the mechanism of the surface phenomenon is essential in analyzing the behavior of liquid crystal molecules on the alignment layer. We measured the temperature dependence of polar anchoring strength on the surface of alignment layers with or without adsorption layer to explain the surface phenomena. As a result, we clarified the polar anchoring strength took a constant value without depending at the temperature in the alignment layer with the adsorption layer, and it decreased as the temperature of the LC cell increased without the adsorption layer.
