  • Publication number: 20180120628
    Abstract: A display apparatus has a display panel having a display region, a light shielding region surrounding the display region, and an outer region located outside of the light shielding region; a support frame disposed at a rear surface side of the display panel, the support frame including a panel supporting portion which supports a peripheral portion of the display panel from a rear side, and an extension beginning from the panel supporting portion and extending away from the display panel; and a light shield disposed at the rear surface side of the display panel, the light shield including a light-shielding portion which is disposed between the display panel and the support frame, the light-shielding portion extending so as to overlap at least a portion of the light shielding region and the outer region of the display panel as viewed from a normal direction of the display panel, and a fixture portion beginning from the light-shielding portion and extending away from the display panel, the fixture portion being

  • Patent number: 9588283
    Abstract: Provided are a light source device which includes a light guide plate configured to emit light made incident thereon through one surface thereof, a reflection sheet which has one surface facing the other surface of the light guide plate and is configured to reflect the light made incident on the light guide plate to one surface side of the light guide plate, and an opposite member oppositely disposed to the other surface of the reflection sheet, such that an occurrence of wrinkles and deflection in the reflection sheet may be prevented with a simple configuration, while surely fixing the position of the reflection sheet, and a display apparatus including the light source device. The reflection sheet includes a first reflection sheet piece and a second reflection sheet piece, wherein the first reflection sheet piece is pinched by the light guide plate and the back cover, and the second reflection sheet piece is held by the first reflection sheet piece.

  • Patent number: 8277066
    Abstract: A lighting device 12 for a display device of the present invention includes tubular light sources 17 provided in a parallel arrangement and covering members 20 that covers respective ends of the tubular light sources 17. Electrodes 41 are provided at ends of the tubular light sources 17. Electrical terminals 24 for electrically connecting to the electrodes 41 are assembled to the covering members 20. Namely, the covering members 20 have an electrical connection function for connecting the tubular light sources 17 to an external power source in addition to a covering function that is its primary function for covering the ends of the tubular light sources 17 so that they are not viewed. With this configuration, efficiency of the assembly work can be improved and reliable power supply to the tubular light sources 17 can be provided.

  • Publication number: 20120008063
    Abstract: An object of the present invention is to provide a liquid crystal display device capable of uniformly irradiating the entire liquid crystal panel with light (that is, capable of preventing light irradiation non-uniformity that can be recognized by viewers), without excessively increasing the number of point light sources (LEDs). In the liquid crystal display device of the present invention, in a backlight substrate region where a plurality of point light sources (L1 to L8) are disposed in a grid arrangement pattern, a position which is within a virtual rectangular region surrounded by four adjacent point light sources, and which is furthest from each of the adjacent point light sources is defined as an anisotropy reference position (G1 to G3). Light emitted from the point light source closest to the anisotropy reference position is selectively diffused in a direction toward the reference position (G1 to G3) by the anisotropic optical member (82), thereby realizing the optical anisotropy is that direction.
