Abstract:
Disclosure is a method for asymmetrically aligning polarizer and rubbing axes of a fringe field switching liquid crystal display, which removes a ghost image and a rubbing mura, caused by an electric field applied to a panel under a low gray scale and dark state, by twisting an optical axis of a polarizer plate and rubbing optical axes of upper and lower plates. The Disclosure aligns polarizer and rubbing axes of a lower plate into which polarizing light is incident in such a manner that an angle formed between the polarizer and rubbing axes is a first predetermined angle and aligns polarizer and rubbing axes of an upper plate through which the polarizing light passes via a liquid crystal in such a manner that an angle formed between the polarizer and rubbing axes is a second predetermined angle.
