Abstract:
A reflection type liquid crystal display device comprising:a liquid crystal cell having an upper substrate, a lower substrate and a liquid crystal layer provided between the upper and lower substrate; a polarizing film provided in a side of the upper substrate in the liquid crystal cell; light reflecting means provided in a side of the lower substrate in the liquid crystal cell; and an optical member provided between the polarizing film and the liquid crystal cell, the optical member having a retardation axis when it is viewed in a normal direction, wherein an angle between an absorption axis of the polarizing film and the retardation axis of the optical member is within the range of about 88Â° to about 92Â°, wherein the optical member is of a hybrid tilt type, the optical member having a refractive index â€œnxâ€  in the direction of â€œxâ€ , a refractive index â€œnyâ€  in the direction of â€œyâ€ , and a refractive index â€œnzâ€  in the direction of â€œzâ€ , the direction of â€œyâ€  falling within a surface of the optical member.
