Patent ID: 7573545

Claim:
A method of manufacturing a liquid crystal display device that has a reduced color shift problem at a wide viewing angle when compared to a liquid crystal display device having a single-side biaxial compensation film, the method comprising: providing a liquid crystal display panel having a first side and a second side opposite the first side; disposing a C-plate phase retardation compensation film on the first side of said liquid crystal display panel, said C-plate phase retardation compensation film having an optical compensation value of R th1 , which is derived from the formula [(n x1 +n y1 )/2−n z1 ]×d 1 , wherein n x1 , n y1 , and n z1 are refractive indexes for the C-plate phase retardation compensation film in a first direction, a second direction, and a third direction respectively, the first, second, and third directions each perpendicular to the other, the third direction normal to the surface of the C-plate phase retardation compensation film that is parallel to the adjacent first side of the liquid crystal display panel; and disposing a biaxial compensation film on the second side of the liquid crystal display panel, the biaxial compensation film having a first optical compensation value of R th2 , the sum of R th1 and R th2 substantially equal to 271 nm.
