An IPS-LCD comprising:
- a liquid crystal panel comprising a top substrate, a bottom substrate, and a liquid crystal cell disposed between the top substrate and the bottom substrate and filled with liquid crystals having a positive dielectric anisotropy, the liquid crystal panel operating in an IPS mode;
- a first polarizer attached to one surface of the liquid crystal panel and in which an absorption axis of a polarizing element is arranged in parallel to an optical axis of the liquid crystal cell;
- and
- a second polarizer attached to the other surface of the liquid crystal cell and having a polarizing element an absorption of which is arranged perpendicular to the optical axis of the liquid crystal cell,
- wherein the second polarizer comprises a polarizing element and a retardation film laminate attached to a surface of the polarizing element, and the retardation film laminate includes a combination of a +B film and a −B film or a combination of a +B film and a +A film.
