Abstract:
The present invention is directed to a VA-mode liquid crystal display panel wherein, by radiating light such as ultraviolet rays to a first alignment film, main chains in molecules of the alignment film are arranged to form a first slow axis. By also radiating the light to a second alignment film, a second slow axis is formed. The first slow axis and the second slow axis are arranged to cross each other. When an electric field is applied to a liquid crystal layer, liquid crystal molecules tilt in the direction which crosses the extending direction of projections formed on a substrate. The projections are formed such that the direction along which the liquid crystal molecules tilt and a first slow axis or a second slow axis differ from each other.
