  • Patent number: 7667786
    Abstract: Backlight with which the uniformity of brightness within a display area of a concavely curved liquid crystal display device is improved while fulfilling the demand for slimmer liquid-crystal display devices, as well as curved liquid-crystal display device including such a backlight. The shape of a frame, an optical sheet, and a scattering plate constituting the backlight unit is the same concavely curved shape as that of the concavely curved panel; and the liquid-crystal panel, the optical sheet, and cold-cathode luminescent lamps are arranged such that the concavely curved panel, the surface of a frame constituting the backlight unit that faces the concavely curved panel, an optical sheet surface, and a surface including the tube center axes of a plurality of cold-cathode luminescent lamps are parallel to each other.

  • Patent number: 7609355
    Abstract: Liquid-crystal display device with a concavely curved panel in which a reflective plate is installed with which a uniform brightness of the screen of the liquid-crystal device with curved screen can be maintained and brightness non-uniformities can be remedied, without making the outer shape of the liquid-crystal display device large. In a liquid-crystal display device having a structure in which a concavely curved panel is held by spacers having a curved shape that are installed on a backlight unit, a reflective plate or reflective sheet is attached to all those inner walls formed by an inner space enclosed by the concavely curved panel, the spacers and the backlight unit that are formed by components that are installed between the curved panel and the backlight unit and that are formed by components that are not transmissive to light that is emitted from the light source.
