Fringe-field switching (FFS) liquid crystal displays (FFS-LCDs) have excellent properties such as a wide viewing angle, high definition, and a low voltage drive. However, FFS-LCDs have a problem, wherein, the display quality deteriorates easily. Even though the asymmetrical electrode structure in an FFS-LCD is considered to be the cause, this problem is not completely understood. Finite-element-method (FEM) simulation studies show that the resistivities of all the materials (a liquid crystal layer, an alignment layer, an insulating layer) that constitute the LCD have an influence.
