ABSTRACT:
An active matrix substrate is provided to be opposed to a counter substrate with a liquid crystal layer therebetween, the liquid crystal layer being in an OCB mode in which orientation is spray orientation when no voltage is applied and the orientation is changed to bend orientation when a voltage is applied. A storage capacitor bus line is provided on a pixel electrode so as to be opposite to the counter substrate and an opening is provided at a part of the pixel electrode at a region where the pixel electrode and the storage capacitor bus line intersect. A liquid crystal control circuit and a relay circuit are provided for applying a transition voltage to the storage capacitor bus line so as to apply an electric field between the pixel electrode and the storage capacitor bus line, and after a certain period in which liquid crystal molecules have responded, applying a transition voltage to the counter electrode so as to apply an electric field between the pixel electrode and the counter electrode.
