    Abstract: Disclosed is an OCB mode LCD device. The OCB mode LCD device includes a liquid crystal cell interposed between substrates, which are rubbed in a predetermined direction, an upper phase delay film aligned above the liquid crystal cell, an upper circular polarizing plate aligned below the upper phase delay film, a lower phase delay film aligned symmetrically to the upper phase delay film, and a lower circular polarizing plate aligned symmetrically to the upper circular polarizing plate and including an optical axis perpendicular to that of the upper circular polarizing plate. The optical axis direction of the polarizing plate is the same as the rubbing direction of the liquid crystal cell, thereby compensating for the phase delay caused by the liquid crystal molecules having the bend structure and realizing the completely dark state while ensuring wide viewing angle characteristics.
