Abstract
A liquid crystal display panel confines liquid crystal between a first orientation film over pixel electrodes and a second orientation film over a common electrode, and differently oriented areas of the first orientation film form boundaries extending over the pixel electrodes and between the pixel electrodes and gate/drain bus lines so as to align electric lines of force in the electric field with directions of liquid crystal molecules on both sides of each boundary, thereby stably controlling a disclination line at a predetermined position outside of open areas over the pixel electrodes.
