Abstract
An absorption current flowing in liquid crystal cells has been measured in order to detect the behavior of impurity ions. The measured current is proportional to t -1 for the region in the initial few seconds. These results agree with the theoretical solution in which the diffusion term in approximation is ignored. The saturated charge density of a surface double layer is about 8.7×10-5 C/m2, which is in the same order as that estimated in a previous paper, 2×1011 ions/cm2. The electric double layer model is also demonstrated.Keywords
