Flicker phenomena in fringe-field switching liquid crystal displays (FFS-LCDs) were studied by finite element method simulations of the transport phenomena of ions, flexoelectric effect, and interfacial polarization. It was found that the influential cause of the flicker phenomena is the charge accumulated at the interface between LC and polyimide material.
