description PURPOSE: A light leakage free liquid crystal display device is provided to control a bending direction of a liquid crystal panel by designing the contraction rates of polarization plates of upper/lower substrates to reduce the degree of bending the liquid crystal panel, thereby reducing light leakage. CONSTITUTION: An upper polarization plate(101) and a lower polarization plate(111) have phase difference films, protective films, and adhesives. The protective films are laminated on both sides of the phase difference films. The adhesives are bonded with a liquid crystal panel. A backlight unit(140) is installed on a rear side of the liquid crystal panel. The backlight unit emits light onto the entire surface of the liquid crystal panel. A case component couples the liquid crystal panel with the backlight unit.
