Abstract
Disclosed is a fringe field switching mode 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; a transparent counter electrode formed on the inner surface of lower substrate; a transparent pixel electrode formed on the inner surface of the lower substrate, forming a fringe field with the counter electrode to drive most of liquid crystals; and a horizontal alignment layer interposed between the substrates and liquid crystal layer, having a predetermined rubbing axis, wherein a retardation of the liquid crystal layer is 0.3 to 0.45 &mgr;m.
