Abstract

The present invention relates to an in-plane switching mode liquid crystal display. More precisely, the present invention relates to an in-plane switching mode liquid crystal display including a first polarizing plate, a second polarizing plate and a liquid crystal cell, designed to have wide viewing angle and to be economical, 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 a slow axis of a compensation film of the first polarizing plate to be parallel to the liquid crystal alignment and to an absorption axis of a polarizer. The present invention can implement mass production of thin liquid crystal displays with high yield (reducing defect ratio due to foreign substances or impurities) and can provide a very large liquid crystal display with its possibility to produce larger, coupled polarizing plate 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.
