Patent ID: 8094272

Claim:
A liquid crystal display comprising: a vertically aligned liquid crystal cell having first and second surfaces opposite each other and having a liquid crystal material with negative dielectric anisotropy interposed therebetween; first and second polarizers attached to the first and the second surfaces of the liquid crystal cell, respectively; and a compensation film comprising a first biaxial compensation film disposed between the first surface of the liquid crystal cell and the first polarizer and having different refractive indexes in three directions; wherein the difference between the summation of the retardation value of the compensation film and the first and second polarizers, and the retardation value due to birefringence of the liquid crystal cell is equal to or less than about 15% of the retardation value due to birefringence of the liquid crystal cell, and wherein the retardation value of the compensation film is (nxc1−nzc1)*dc1, where a z-axis is perpendicular to the first surface of the liquid crystal cell, an x-axis is the same direction as the direction having the largest refractive index in the compensation film, nxc1 and nzc1 are refractive indices along the x-axis and the z-axis of the compensation film, respectively and dc1 is a thickness of the compensation film, respectively.
