  • Patent number: 8339540
    Abstract: A reflection sheet is made of material having a coefficient of thermal expansion different from that of an LED substrate. A fixing member and a retaining member extend through the reflection sheet and the LED substrate so as to fix the reflection sheet and the LED substrate. The reflection sheet includes a fixing hole into which the fixing member is inserted, a retaining hole into which the retaining member is inserted, and LED holes within which light emitting diodes are disposed, respectively. Retaining of the reflection sheet by the retaining member has, compared to fixing of the reflection sheet by the fixing member, a higher degree of freedom of movement in a direction along a surface of the reflection sheet. The LED holes located in positions far from the fixing hole are larger than the LED holes located in positions close to the fixing hole.

  • Publication number: 20110007095
    Abstract: [Object] It is an object of the present invention to provide an image display device capable of properly setting a display direction of an image in accordance with a user's will. [Constitution] When a user holds a cell phone such that a first switching key 8 comes closer to the user's body, this makes the user push the first switching key 8. If the user pushes the first switching key 8, a CPU 100 displays a display image such that a display direction becomes a first direction where the first switching key 8 comes downside. If the user holds the cell phone such that a second switching key 9 comes closer to the user's body, this makes the user push the second switching key 9. If the user pushes the second switching key 9, the CPU 100 displays the display image such that the display direction becomes a second direction where the second switching key 9 comes downside.

  • Patent number: 7688399
    Abstract: An image display apparatus including a light source unit, a liquid crystal display panel, an illumination optical system leading light from the light source unit to the liquid crystal display panel, and a display optical system leading light from the liquid crystal display panel to an observer. The illumination optical system and the display optical system share an optical surface having dielectric multilayer films and being concave toward the liquid crystal display panel on a plane including a center ray corresponding to an angle of view. The optical surface reflects light from the light source unit for leading the light to the liquid crystal display panel while transmitting light reflected from the liquid crystal display panel. On the plane including the center ray, the brightness of the light-emitting surface of the light source unit is reduced toward the optical surface smaller than that in the remote from the optical surface.
