Abstract

The invention discloses a fringe field switching (FFS) liquid crystal display and a color film substrate. The liquid crystal display comprises an upper substrate, a lower substrate and a liquid crystal layer arranged between the upper substrate and the lower substrate in a sandwiched mode. The lower substrate comprises public electrodes and pixel electrodes, and each pixel electrode comprises at least one branch electrode and a terminal electrode used for connecting the branch electrodes. One auxiliary electrode corresponding to each terminal electrode is arranged on the upper substrate. Due to the existence of the auxiliary electrodes, unexpected electric fields between the terminal electrodes and the public electrodes are effectively weakened, distribution of liquid crystal molecules at the positions of the boundaries of the pixel units corresponding to the terminal electrodes is stabilized, therefore, disclination lines are improved, display is even, high-quality frames are provided, the width of a black matrix can become small, and the aperture opening rate can be increased.

Description

technical field [0001] The invention relates to a liquid crystal display, in particular to a fringe field switching mode liquid crystal display and a color filter substrate. Background technique [0002] At present, in the technical field of liquid crystal display devices, there are mainly IPS (In Plane Switching, lateral electric field switching) liquid crystal displays and FFS (Fringe Field Switch, fringe field switching) liquid crystal displays that adopt the transverse electric field method. In the FFS liquid crystal display, the upper electrode layer and the lower electrode layer are insulated from each other by an insulating layer, the lower electrode layer is used as a common electrode layer, and the upper electrode layer is used as a pixel electrode layer, and for example, slits are formed on the upper electrode layer, so as to This acts as an opening for the electric field to flow through. IPS / FFS liquid crystal display transmittance formula T=T o sin 2 (2Φ) sin ...
