  • Patent number: 7733450
    Abstract: A liquid crystal display (LCD) device includes first and second substrates, an electrically controlled birefringence (ECB) mode liquid crystal layer between the first and second substrates, a first polarizer under the first substrate, a second polarizer on the second substrate, and a first compensation film between the first and second polarizers, wherein an optical transmission axis of the first compensation film is set at a 90° angle with respect to an alignment direction of the ECB liquid crystal layer.

  • 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.
