Abstract
A liquid crystal display panel is placed on a fixed base and an anisotropic film is set in a position relative to the orientation layer of the display panel. Linearly polarized light is directed to the panel and the anisotropic film and light passing through them are detected. According to the intensity of the detected light, the angle of orientation of the anisotropic film is adjusted relative to the orientation layer. Angular misalignment, which may exist between the anisotropic film and the orientation layer, is minimized.
