Abstract

A display device includes a light supplying unit generating light and a liquid crystal panel having a liquid crystal layer including liquid crystal molecules aligned substantially parallel to the plane of a pair of substrates by anti-parallel rubbing when no voltage is applied to the panel. Bias voltage corresponding to maximum gray level of the panel is determined between threshold voltage of the liquid crystal layer and 40% of maximum voltage.
