  • Optical sheets formed with two-part protrusions on its edges
    Patent number: 9720162
    Abstract: This backlight device 2 is provided with: a light source; a plurality of stacked optical sheets 22, 23, and 24 through which the light from the light source passes; and a frame member 28 to which the plurality of optical sheets 22, 23, and 24 are affixed. The respective plurality of optical sheets 22 to 24 is provided with protrusions 221, 231, and 241 that protrude in a direction parallel to the sheet surface at a portion of the edge thereof. The protrusions 221, 231, and 241 respectively have: first regions 221a, 231a, and 241a that are provided to the root side and that do not overlap the protrusions of the other optical sheets; and second regions 221b, 231b, and 241b that are provided to the tip side and of which at least a portion overlaps the protrusions of the other optical sheets.
