Abstract:
A FFS-LCD comprising:an upper and a lower substrates opposed to each other with a predetermined distance; a liquid crystal layer interposed between the substrates, comprising liquid crystal molecules of positive dielectric anisotropy between 4 and 15, wherein the maximum transmittance is achieved when a retardation of the liquid crystal layer having the positive dielectric anisotropy is 0.3 to 0.45 &mgr;m and when the major axis of the positive anisotropic liquid crystal molecules is twisted parallel to the direction of and in the presence of a fringe field; a counter electrode disposed on the inner surface of the lower substrate; a pixel electrode disposed on the inner surface of the lower substrate, forming the fringe field with the counter electrode to drive the liquid crystal molecules; a first horizontal alignment layer interposed between the lower substrates and the liquid crystal layer, having a predetermined rubbing axis; and a second horizontal alignment layer inter interposed between the upper substrate and the liquid crystal layer, having a predetermined rubbing axis.
