Abstract
A liquid crystal display panel employing an in plane switching (IPS) mode wherein an alignment direction of a liquid crystal is moved on a plane parallel to the surface of the panel. In the panel, electrode patterns are formed on each substrate in such a manner to be opposed to each other. A liquid crystal layer is filled between the substrates provided with the electrode patterns. Alignment films are formed on each of the substrates in such a manner to be positioned between the electrode patterns and the liquid crystal layer. The alignment films allow an alignment direction of the liquid crystal layer to be changed on a plane parallel to the surfaces of the substrates by an electric field applied between the electrode patterns.
