    Abstract: According to one embodiment, a display device includes a liquid crystal display panel having a display surface, a cover panel overlaid on a display surface, a backlight unit opposed to the liquid crystal display panel, a case covering the backlight unit and the liquid crystal display panel, and including at least a part fixed to the cover panel; and an adhesive provided on the cover panel along the liquid crystal display panel. The adhesive includes a surface opposite to the cover panel, a first area on the surface, and a second area on the surface, and locates on an inner side closer to the liquid crystal display panel than the first area. The part of the case is adhered to the second area. The adhesive is formed in a frame shape with an inner opening surrounding the liquid crystal display panel without contacting the liquid crystal display panel.

    Abstract: An illumination device includes: a first light guide plate including a first and a second scattering portions and a first region not having the first and second scattering portions arranged therein; a second light guide plate including a third and a fourth scattering portions; a first illuminator emitting light to a first side surface of the first light guide plate; a second illuminator emitting light to a second side surface opposite to the first side surface; a third illuminator emitting light to a third side surface of the second light guide plate; and a fourth illuminator emitting light to a fourth side surface opposite to the third side surface. The second light guide plate overlaps the first light guide plate as viewed from a direction of the thicknesses thereof. The third and fourth scattering portions overlap the first region as viewed from the direction of the thicknesses.
