Abstract

The present invention relates to an in-plane switching mode liquid crystal display, and more preciesly, an in-plane switching mode liquid crystal display including an upper polarizing plate, a lower polarizing plate and a liquid crystal cell, designed to have wide viewing angle because the optical properties of the compensation film are determined by changes of the polarization state of liquid crystal alignment on a Poincare Sphere, and the contrast in the inclined visual direction is improved due to the configuration of a slow axis of a first and second compensation films, absorption axis of the polarizer, and the liquid crystal alignment. The present invention can implement mass production of thin liquid crystal displays with high yield (reducing defect ratio due to foreign substances or impurities) since it is possible to ensure a wide viewing angle with only one sheet of compensation film for the upper polarizing plate and the lower polarizing plate.
