ABSTRACT:
A liquid crystal display device comprising a liquid crystal panel in which liquid crystals having negative dielectric anisotropy are interposed between upper substrate and lower substrate that have been vertically oriented on the surface, the orientation of the liquid crystals being almost vertical with no applied voltage, almost horizontal when a predetermined voltage is applied, and tilted when a smaller voltage than the predetermined voltage is applied; a first polarizer and a second polarizer disposed on both sides of the liquid crystal panel such that the absorption axes of the polarizers are perpendicular to each other; a first retardation film disposed between the liquid crystal panel and the first polarizer; and a second retardation film disposed between the liquid crystal panel and the second polarizer, wherein the polarizer comprises a polarizing film and a pair of protective films having the polarizing film in between, and wherein at least one of the protective films is a cellulose acylate film satisfying:in-line-formulae description="In-line Formulae" end="lead"?0≦Re(630)≦10 and |Rth(630)|≦25.in-line-formulae description="In-line Formulae" end="tail"?
