  • Patent number: 7050020
    Abstract: A 3D image/2D image switching display apparatus is provided with a liquid crystal display unit and first and second lenticular lenses. To display a 3D image, the first lenticular lens is arranged in such a way that the optical axis of the first lenticular lens coincides with the optical axis of the second lenticular lens so that pixels for a left eye display an image for a left eye and pixels for a right eye display an image for a right eye. To display a 2D image, the first lenticular lens is arranged in such a way that the optical axis of the first lenticular lens is shifted from the optical axis of the second lenticular lens by half a lens pitch so that the pixels for the left eye and the pixels for the right eye display the same image independently.

  • Publication number: 20050206600
    Abstract: Provided is a structure which is capable of narrowing a semiconductor chip in width and a display device which is narrowed in frame by using the same. In the structure of a semiconductor chip provided such that the semiconductor chip is mounted on a glass substrate and a plurality of power lines (a first wiring and a second wiring) of the semiconductor chip are extended in a continuous direction so as to form, the structure of the semiconductor chip comprises the power lines with different electric potentials, which is formed by overlapping. Rather than making a capacity at the overlapped area of wirings and forming the wiring alone, a wiring which is narrowed in width may be achieved.

  • Patent number: 6842209
    Abstract: A liquid crystal display device comprising a first polarizing sheet (16a), a color filter layer (6) formed on glass sheet (18), a second polarizing sheet (16b), three-layered HPDLC (17) formed below the liquid crystal layer (1) and acting as a reflective structural layer having a reflectivity changed electrically, and a backlight unit as the lowermost layer. Each layer of the three-layered HPDLC (17) is composed of a liquid crystal droplet layer polymer layer and reflects blue, green, red by Bragg reflection. When voltage is applied to the three-layered HPDLC (17), the reflectivity of liquid crystal droplet layer of each layer change, so that the HPDLC can be made transparent by equalizing the reflectivities of the liquid crystal liquid droplet layer to those of polymer layers.
