Abstract
The present invention discloses a fringe field switching mode liquid crystal display. The disclosed comprises: a lower and an upper substrates disposed opposite to each other at a predetermined distance, having transparency; a counter electrode and a pixel electrode disposed on the inner surface of the lower substrate with a gate insulating layer interposed and made of transparent conductors, forming a fringe field when a electric field is applied; a black matrix and color filter formed on the inner surface of the upper substrate; an ITO layer disposed on the inner surface of the upper substrate which has the black matrix and the color filter therein; and a liquid crystal layer interposed between the lower and the upper substrates, including a plurality of liquid crystal molecules of negative dielectric anisotropy. In the FFS mode LCD of the present invention, the counter electrode has a plate shape and the pixel electrode has a slit shape. And the counter electrode has one or more grooves whose width is smaller than that of the slit of the pixel electrode, preferably 2 or 3 &mgr;m and the ITO layer includes a window region therein.
