  • Patent number: 7872717
    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.

  • Patent number: 7633572
    Abstract: A liquid crystal display (LCD) includes a first substrate having an array of wiring lines and pixel regions. The pixel regions have pixel electrodes, thin film transistors with drain electrodes, and storage capacitors. The LCD also includes a second substrate having color filters, black matrices, opened regions to receive external light positioned in regions in which the black matrices are not positioned, and transparent common electrodes. Liquid crystal is between the first and second substrates. The opened regions correspond to first regions in which the drain electrodes and the pixel electrodes are connected and second regions in which the storage capacitors are positioned. In one embodiment, the liquid is driven in a normally white mode when the LCD is driven in a transmissive mode, and is driven in a normally black mode when the LCD is driven in a reflective mode.
