Abstract

Provided is a Fringe Field Switching (FFS) mode Liquid Crystal Display (LCD). In the FFS mode LCD, a lower substrate, an upper substrate and a liquid crystal layer interposed between the substrates are included, each pixel region is defined by gate lines and data lines formed to cross each other on the lower substrate, and switching devices are disposed at intersections of the gate lines and the data lines. The FFS mode LCD includes a transparent pixel electrode, and a transparent common electrode disposed apart from the transparent pixel electrode by an insulating layer interposed between the transparent pixel electrode and the transparent common electrode, in the pixel region to adjust transmittance by applying an electric field to the liquid crystal layer, the transparent common electrode has a plurality of bars having a predetermined width in a direction substantially parallel to the data lines, the transparent common electrode has a first bar formed to cover the data lines and a second bar formed adjacent to the first bar in a central area of the pixel region, a distance between the first bar and the second bar is larger than a distance between bars formed in the pixel region,…
