Abstract

We have studied the dynamic stability of a liquid crystal (LC) in an adjacent active region near the edge of a pixel slit according to the horizontal electric field generated by the data signal for the fringe field switching (FFS) mode. The horizontal component of a fringe electric field becomes strong as the distance between the common electrode and the data bus line decreases. Therefore, the disclination lines (DLs), which are formed near the pixel edge, barely intrude an active region. Moreover, the LC director existing in this region becomes stable and has a large twist angle. This indicates that the LC dynamic stability near the pixel edge is markedly affected by the horizontal electric field of a strong data signal.
