  • Patent number: 11363844
    Abstract: A mask having an inner surface facing a wearer and an outer surface located opposite to the inner surface has first to fourth filters. The first filter is disposed on the outer surface of the mask and has air permeability and a water absorption capacity of 100% or more and less than 1000%. The second filter is layered on the first filter on the side of the inner surface of the mask and has air permeability and a water absorption capacity of less than 30%. The third filter is layered on the second filter on the side of the inner surface of the mask and is formed of an electret filter having air permeability and a water absorption capacity of less than 50%. The fourth filter is disposed on the inner surface of the mask and has air permeability.

  • Patent number: 8419202
    Abstract: The present invention relates to the rigidity of a backlight chassis and is applicable to a liquid crystal display device including a backlight chassis and a light source located in the backlight chassis. A liquid crystal display device according to the present invention includes a backlight chassis (24), located to face a rear surface of a liquid crystal panel (10), for supporting a light source (22) for illuminating the rear surface of the liquid crystal panel (10). The backlight chassis (24) is a substantively flat plate-like member with upright peripheral portions (24a through 24d), and includes grooves (71 through 74) in a first area (A1) and a second area (A2), which are separated from each other by a border line (L) set on the backlight chassis (24). According to the present invention, the entirety of the backlight chassis is unlikely to be deflected.
