ABSTRACT:
A method of aligning a TFT plate and a color filter plate of a liquid crystal display is described. The TFT plate has a capacity storage area formed thereon. The capacity storage area is designed within a black matrix area on the color filter plate. After a rubbing process, a bump in the capacity storage area of the TFT plate causes a first abnormal rubbing area, which is adjacent to a side of the bump. The color filter plate is shifted first, so that the first abnormal rubbing area is covered with a black matrix in the black matrix area on the color filter plate. The TFT plate is then aligned with the color filter plate. As a result, corner image sticking in a frame of the liquid crystal display is avoided.
