Abstract
The present invention discloses a fringe field switching (FFS) liquid crystal display and a color filter substrate. The liquid crystal display includes an upper substrate, a lower substrate, and a liquid crystal layer sandwiched between the upper substrate and the lower substrate. The lower substrate includes a common electrode and a pixel electrode, and the pixel electrode includes at least one branch electrode and an end electrode for connecting the branch electrode; and an auxiliary electrode corresponding to the end electrode is arranged on the upper substrate. In the presence of the auxiliary electrode, unwanted electric fields between the end electrode and the common electrode are effectively attenuated, and arrangement of liquid crystal molecules at the boundary of a pixel element where the end electrode is located is stabilized, so that disclination lines are improved, pictures are displayed uniformly with high quality.
