Since the application of liquid crystal begun in 1960s, the related manufacturing technology has already been considerably mature, but there are still many problems to desiderate to be resolved. The charge-accumulation of TN-LCD is the one of quite intractable problems in producing of LCD. Because quantitative measurement of charge-accumulation is hard to be done, the problem is still up in the air. Here the charge accumulation of LCD was analyzed from the opinion of the dielectric physics in this paper, and it was found that the accumulated charge can be produced in the interface when the ratio of dielectric constant and conductivity for alignment layer doesnt equal to that of LCD layer. The larger the ratio of dielectric constant and conductivity, the higher charge accumulation, and if the ratio of dielectric constant and conductivity equals to each other, there is no charge to be accumulated, this will be helpful to solve the problems such as image sticking, slow response etc.
