A display device is provided and includes a liquid crystal display panel; and a backlight device opposed to the liquid crystal display panel; the backlight device including a frame-shaped structure with a first surface and a second surface, the second surface facing the liquid crystal display panel and being located between the liquid crystal display panel and the first surface; a reflective sheet adhering to the first surface with a first adhesive layer; and a light-shielding member covering a side surface of the liquid crystal display panel.

Display device

A display device is provided and includes a liquid crystal display panel; and a backlight device opposed to the liquid crystal display panel via a polarizing plate; the backlight device including a frame comprising at least four bars; a first adhesive layer provided on one surface of the bars; a reflective sheet; a lightguide disposed on the reflective sheet in the frame; and a light source disposed in the frame and configured to emit light to the lightguide, wherein the frame includes a portion that is exposed from the liquid crystal display panel in a plan view, and a resin adhesive layer having a light-shielding property covers an external surface of the liquid crystal display panel and the portion of the frame.

According to one embodiment, an illumination device includes a light source disposed along a first direction, a light guide plate including a first end and a second end, the second end being positioned to be opposite to the first end in a second direction which crosses the first direction, a frame disposed along the second end and including an inner surface and an upper surface, and an adhesion member disposed on at least the upper surface of the frame, wherein the light source is disposed at the first end along the first direction, at least the inner surface of the frame is a light absorbing surface, and the adhesion member is light transmissive.

Illumination device and liquid crystal display device

A backlight device is provided and include frame formed of sheet material including at least four bars; first adhesive layer provided on one surface of the bars; reflective sheet attached to frame with first adhesive layer; second adhesive layer is provided on another surface opposed to the one surface of the bars; optical member including lightguide plate disposed on reflective sheet in frame; and light source disposed in frame and configured to emit light to optical member, wherein thickness of second adhesive layer provided on three successive bars of frame along three sides of lightguide plate is greater than thickness of first adhesive layer provided on four bars of frame.

Backlight device and display device

A backlight device is provided and includes a frame formed of a sheet material; a first adhesive layer provided on one surface of the frame; a reflective sheet attached to the frame with the first adhesive layer; an optical member disposed on the reflective sheet in the frame; and a light source disposed in the frame and configured to emit light to the optical member, wherein in at least a part of the frame, a width of the frame and a width of the first adhesive layer are equal to each other, and at least an internal surface of the frame and an internal surface of the first adhesive layer are flush with each other.

According to one embodiment, a liquid crystal display device includes a liquid crystal panel and a backlight device. The backlight device includes a case with a bottom plate and a side plate, a light guide on the bottom plate, and a light source device. The light source device includes a wiring substrate and a light-emitting element on the wiring substrate. The wiring substrate includes a mounting portion on which the light-emitting element is mounted, a connection wiring portion on a back surface side of the bottom plate, and a joint portion which joints the mounting portion and the connection wiring portion together. The joint portion extends from an inside to an outside of the case through a gap between the side plate of the case and the liquid crystal panel.
