Abstract: A lighting device includes a light guide plate including a groove on one of a pair of plate surfaces thereof, the groove dividing the one of the pair of plate surfaces into areas each of which includes a portion of an outer peripheral surface, and a light source providing light such that the light enters each of the areas through the portion of the outer peripheral surface thereof. The light source is configured to control light that enters each of the areas such that luminance of light exiting the light guide plate through a light exit surface that is one of a pair plate surfaces thereof is made different in each of the areas.

Abstract: A display device includes a display module, a module holder, and at least one spacer. The display module includes a display panel and a panel holder. The display panel is configured to display images. The panel holder includes a frame portion that surrounds the display panel and a pair of panel holding portions to sandwich an outer edge portion of the display panel in a thickness direction of the display panel. The module holder includes a pair of module holding portions to sandwich an outer edge portion of the display module in the thickness direction. The spacer is disposed between the frame portion and at least one of the module holding portions so that the at least one of the module holding portions remains separated from at least one of the panel holding portions.

Abstract: In a display unit, measures against dropping of screws can be realized at low cost. The display unit includes: a wiring substrate in which wiring that is led out from a display panel is provided; a screw that fixes the wiring substrate to the display unit; and a substrate cover that covers the wiring substrate. The substrate cover has a screw covering region that covers a head of the screw, and part of the periphery of the screw covering region is separated from the other area of the substrate cover.

Abstract: In a lamp unit (1), a conductive section (2) is formed by directly extending a layer structure of a reflective member (42) from (i) one end of a square U-shape of a part of the reflective member (42) that is closest to a power feeding section for feeding power to the lamp unit (1) toward (ii) a light emission side of the lamp unit (1) and further folding back the extended portion 180 degrees in a direction opposite to the direction that it extends from the reflective member (42). The conductive section (2) is provided with a screw hole (2a) through which the reflective member is connected to another object. This achieves a lamp unit in which, even if a reflective member is fixed to another object with a screw for conduction with an external conductor, a reflective layer is less likely to peel off.

Abstract: A resin frame (2) is disposed on an emission surface (43) side of a light guide plate (4) through at least one optical sheet (3). A protrusion (25) facing an end surface (45) adjacent to the emission surface of the light guide plate is provided upright on the resin frame. The protrusion is elastically deformable towards the opposite side to the light guide plate where the protrusion faces. Since the protrusion elastically deforms to absorb the extension of the light guide plate, the light guide plate does not deform. Therefore, it is possible to prevent, for the long term, deformations of the light guide plate resulting from relative changes in the size of the light guide plate due to changes in temperature and humidity.

Abstract: Provided is an illuminating device wherein generation of luminance deterioration and luminance nonuniformity is suppressed. An illuminating device (10) is provided with a light guide plate (3) and an LED (6) stored inside a storing space (10a), and a power supply substrate (8) arranged outside the storing space (10a). An extracting hole (1c) is formed in a region (10b) whereupon the light guide plate (3) at a bottom section (1a) of a case member (1) is placed, and a connecting terminal (7c) of an FPC (7) is extracted to the outside from the inside of the storing space (10a) through the extracting hole (1c).

Abstract: There are provided a light source 16 that emits light, an optical sheet 14 that adjusts the optical path of the light emitted from the light source 16 in such a way that a liquid crystal panel 12 is irradiated with the light from behind, and a frame 13 that permits the optical sheet 14 to be kept in position behind the liquid crystal panel 12. The optical sheet 14 is supported at one point on the frame 13. When the optical sheet 14 is rectangular, advisably it is supported on the frame 13 substantially at the center of one side of the optical sheet 14. For stable fitting, preferably the optical sheet 14 is supported on the frame 13 substantially at the center of that side of the optical sheet 14 which, in actual use, is located at the top with respect to the direction of gravity.
