Abstract: A backlight device includes an LED; a light guide plate that has a light-exiting surface provided at one plate surface, an opposite surface provided at a plate surface on the opposite side to the light-exiting surface, and a light-receiving side face provided at one side face, that is arranged such that the light-receiving side face faces the LED and that guides light from the LED; a chassis having a plate surface arranged so as to face the opposite surface and housing at least the LED and the light guide plate; and an optical sheet that is arranged so as to face the light-exiting surface, that provides light that has exited the light guide plate with an optical function and that has a bent portion that extends further toward the outside than an edge of the light-exiting surface and is bent toward the opposite surface side and as a result covers at least part of a side face of the light guide plate.

Abstract: A backlight unit comprises a light source, a light guide plate and a frame. The light guide plate comprises a light guide and a low-refractive-index layer. The refractive index of the low-refractive-index layer is less than the refractive index of the light guide. A plurality of prisms for gradually reducing the angle of incidence of light coming from the light source with respect to the rear surface of the light guide are provided to the front surface or rear surface of the light guide. A plurality of prisms for totally reflecting forward the light coming from the light source are provided to the rear surface of the light guide plate. The frame comprises walls for surrounding the light source and the light guide plate. The width of the upper side of the walls and the width of the lower side thereof are substantially equal.

Abstract: This illumination device (20) is provided with: a light guide plate (30) that guides the light entering from an entrance surface (30a), and radiates it from an exit surface (30b); and a frame-shaped frame (25) that supports the outer periphery of the light guide plate (30). The light guide plate (30) has: a light guide portion (35) that, in parallel along the optical axis direction (X), is provided with prisms (33) containing an inclined surface (33b) that faces and is inclined with respect to the entrance surface (30a); a low-refractive-index-layer (36) having a lower refractive index than the light guide portion (35); and a light-collecting portion (37) that is provided in parallel along the optical axis direction (X) with prisms (38) that contain an inclined surface (38b) that faces and is inclined with respect to the entrance surface (30a). The frame (25) is formed from a light absorbing material.

Abstract: Provided is a display device which can achieve a thickness reduction and allows a panel protection plate to be replaced with ease. The display device is provided with: a liquid crystal display panel (11) having a display surface (11a); and a case (13) having the liquid crystal display panel (11) housed therein. A panel protective plate for protecting the display surface (11a) of the liquid crystal display panel (11) is formed integrally with the case (13).

Abstract: A flexible circuit board includes: an insulative tape having a pair of long sides and a pair of short sides; a driving IC mounted on the insulative tape; an input terminal for receiving data signals and control signals to be sent to the driving IC; a first output terminal for outputting a signal from the driving IC; a second output terminal for outputting at least some of the data signals and control signals; and first and second power signal terminals for supplying a voltage to the driving IC, wherein the input terminal, the first output terminal, and the second output terminal are provided on one of the pair of long sides, the first power signal terminal being provided on one of the pair of short sides, and the second power signal terminal being provided on the other one of the pair of short sides.

Abstract: A reinforcing plate is made up of a planar member which is composed of a panel fixture portion and connecting parts provided at both ends of the panel fixture portion. A scan signal input circuit substrate for supplying a scan signal to a display panel and a data signal input circuit substrate for supplying data are provided on respective sides of the display panel. The scan signal input circuit substrate has an input connector and electronic parts such as driver ICs etc., mounted thereon. The connecting parts of the reinforcing plate are fixed to the scan signal input circuit substrate so as not to interfere with the electronic parts while the panel fixture portion of the reinforcing plate is fixed to the display panel.
