A display device which is an electro-optical device includes a panel including a first substrate, a second substrate, and a liquid crystal layer and having a display region, a transparent region provided inside the display region, and a frame region provided between the transparent region and the display region. A backlight unit is provided below the panel so as not to overlap with the transparent region. A bezel is provided below the backlight unit so as not to overlap with the transparent region. A cover member is provided above the second substrate so as to overlap with the transparent region. Also, a cap film made of a material different from that of the bezel covers at least a lateral side of the backlight unit in the frame region.

Electro-optical device and electronic equipment

A backlight device is provided and includes case having bottom plate; light guide having front surface as emission surface, rear surface opposed to front surface, and incidence surface that is one of side surfaces of light guide, rear surface facing to bottom plate; light-emitting elements facing incident surface of light guide, each of light-emitting elements having bottom surface and light-emitting surface facing incidence surface of light guide; fixing tape arranged on bottom plate, each of bottom surfaces of light-emitting elements and rear surface of light guide being adhered to fixing tape; and light-shield facing fixing tape through light guide.

Backlight device

A backlight device is provided and includes case having bottom plate; light guide including front surface as emission surface, rear surface opposed to front surface, and incidence surface provided between front and rear surfaces, rear surface being arranged on bottom plate; and light-emitting elements facing incident surface of light guide, wherein light-emitting elements includes first surface provided at bottom of light-emitting elements, and light-emitting surface facing incidence surface of light guide, first surfaces and rear surface are arranged side by side, and fixed to fixing tape attached over first surfaces and rear surface of light guide, and light-shield is facing fixing tape through light guide.

A display device includes a panel, a backlight, and an adhesive tape. The backlight is placed under the panel. The adhesive tape has a light blocking property and is bonded to an end face of the panel and the backlight.

Display device

A display device is provided and includes a display panel comprising a substrate; a case provided on a back side of the substrate, the case having an outer surface; and a flexible wiring board, one end of which is connected to a top surface of the substrate, curved along the outer surface of the case; wherein the flexible wiring board is fixed to a side surface of the substrate and the outer surface of the case with an adhesive.

A display device includes a display panel, a backlight under the display panel, and an adhesive placed so as to extend over a side face of the display panel and a side face of the backlight. An outer face of the adhesive opposite to a face of the adhesive bonded to the side face of the display panel and the side face of the backlight is formed as a flat face along one or both of the side face of the display panel and the side face of the backlight.

Display device and bonding method

A backlight device is provided and includes case having bottom plate; light guide including front surface as emission surface, rear surface opposed to front surface, and incidence surface provided between front surface and rear surface; and light-emitting elements facing incident surface of light guide, wherein light-emitting elements include first surface provided at bottom of light-emitting elements, and light-emitting surface facing incidence surface of light guide, first surfaces and rear surface are arranged side by side, and fixed to fixing tape attached over first surfaces and rear surface of light guide, and light-shielding tape facing fixing tape through light guide and light-emitting elements.

Backlight device and a liquid crystal display device

According to one embodiment, a backlight device includes a case having a bottom plate, a light guide having an emission surface, a second main surface and an incidence surface and arranged on the bottom surface, and a light source unit including a wiring board and light-emitting elements on the wiring board. Each light-emitting element has a mounting surface, a first side surface opposed to the mounting surface, and a light-emitting surface between the mounting surface and the first side surface. Each light-emitting surface faces the incidence surface, and the first side surfaces are arranged parallel to the second main surface, and the light source unit is fixed to the light guide with a fixing tape attached over each first side surface and the second main surface.

Backlight device and liquid crystal display device

According to one embodiment, a display device includes a display panel, a case including a bottom plate opposing a rear surface of the display panel and a side plate stand on the bottom plate and attached to the display panel, a flexible wiring board, one end of which is joined to the display panel, curved around the side plate toward the bottom plate to oppose the bottom plate while, and an adhesive filled between the flexible wiring board and the side plate of the case or between the flexible wiring board and both of the side plate and the bottom plate, to adhere the flexible wiring board onto an outer surface of the case and hold the flexible wiring board in a curved state.

According to one embodiment, a light source device includes a wiring substrate including a mount region, a plurality of light sources arranged and mounted on the mount region of the wiring substrate, and a heat reactive adhesive sheet adhered to the wiring substrate.
