ABSTRACT:
A liquid crystal display device having vertical alignment films formed on pixel electrodes of a thin film transistor substrate and a common electrode of a common electrode substrate, and horizontal alignment films formed in a shape of plural belts on the vertical alignment films. The horizontal alignment film of the thin film transistor substrate and the horizontal alignment film of the common electrode substrate are substantially perpendicular to each other. Accordingly, a liquid crystal layer interposed between the two substrates includes a splay area, a homeotropic area, and hybrid area, wherein the hybrid area is disposed around the splay area and the homeotropic area. Since the hybrid area serves as an alignment transition seed, the liquid crystal molecules of the splay area can be easily changed to have a band alignment. Therefore, it is possible to decrease an alignment transition voltage and to enhance an alignment transition speed.
