  • Patent number: 11067739
    Abstract: Provided are an edge-lit surface light source device and a liquid crystal display device, both of which are capable of two-dimensional local dimming without image contrast being reduced due to stray light. Even when light from LEDs that should be extracted by means of a light extraction pattern provided in a first section of a light guide plate is passed through the first section without being extracted, the light repeatedly strikes on a light absorbing layer formed in a second section, whereby much of the light is absorbed in the second section. Accordingly, little light from the LEDs is extracted from a third section, from which light from LEDs should originally be extracted, with the result that image contrast can be prevented from being reduced due to stray light.

  • Patent number: 11016239
    Abstract: A lighting device includes light guide plates each of which includes a light exit section including a light it surface and a light entering section extending from the light exit section toward a light source row and including an extended end surface as a light entering surface. The light exit section has a thickness dimension that is smaller than that of the light entering section at an extended end thereof. The light guide plates are stacked on each other such that the light exit sections thereof overlap each other seen from a normal direction of the light exit surface. The light entering section of one light guide plate and the light entering section of another light guide plate are disposed next to each other in an arrangement direction of the light sources so as not to overlap each other seen from the normal direction of light exit surface.
