  • Patent number: 9091872
    Abstract: A liquid crystal display accommodates a reflective portion with a concavo-convex reflecting pixel electrode for reflecting incident light from the display face side, and a transmissive portion with a transmissive pixel electrode for transmitting light output from the backlight. In a wide viewing angle region, luminance of the reflective portion is greater than the transmissive portion. In other angle regions, luminance of the transmissive portion is greater than the reflective portion. In a wide viewing field mode, the reflective portion and transmissive portion both perform normal display. In the narrow viewing field mode, the transmissive portion performs normal display, while the reflective portion performs cancelling data display, thereby rendering unviewable the display content of the transmissive portion from beyond a certain viewing angle.

  • Patent number: 9025116
    Abstract: A liquid-crystal display device makes it possible to attach an optical element to a liquid-crystal display panel with high positional accuracy while avoiding or minimizing the enlargement of the picture-frame region (i.e., the non-display region) induced by the formation of markers on the panel and the increase of the fabrication cost. The panel comprises a main substrate, an opposite substrate, and a liquid crystal enclosed in a gap between the main and opposite substrates, wherein a polarizer plate is attached at least to the opposite substrate. Markers for attaching an optical element to the panel are formed at positions that overlap with the polarizer plate in a non-display region on the main or opposite substrate. Alignment direction regulators regulate the alignment of the liquid crystal molecules to a predetermined direction in the vicinities of the markers, allowing light to pass through at least the opposite substrate.

  • Patent number: 8717266
    Abstract: A liquid crystal display device comprises a liquid crystal panel including sub-pixels and a back light for irradiating light to the back surface of liquid crystal panel. A transmission sub-pixel can be switched into an image display state which can allow irradiated light to exit, and a black display state which does not allow irradiated light to exit. A mirror sub-pixel can be switched between a mirror state which can allow reflected light to exit and a non-mirror state which does not allow reflected light to exit, independently of the transmission sub-pixel. A control unit places each transmission sub-pixel into the image display state or black display state, and places each mirror sub-pixel into the mirror state or non-mirror state.
