First Claim
1. A lighting device comprising:
- a light source;
a light guide plate including a light exit surface, an opposite surface, and a light entrance surface opposite a light emitting surface of the light source to guide light from the light source toward the light exit surface;
a chassis including a plate shaped portion at a side adjacent to the opposite surface of the light guide plate;
a light source mounting member to mount the light source, the light source mounting member including a bottom plate including a first plate surface and a second plate surface, the first plate surface in surface-contact with a surface of the plate shaped portion opposite from a surface thereof facing the light guide plate, a portion of the second plate surface exposed to an external side;
a display panel including a display surface to display an image using light from the light exit surface of the light guide plate;
a frame-shaped member on a display surface side of the display panel and holding the display panel such that the display panel is between the frame-shaped member and the light guide plate, the frame-shaped member providing an external appearance of the display device;
a fixing member fixing the bottom plate to the frame-shaped member, whereinthe light source mounting member is separated from the frame-shaped member.

Abstract
A backlight device 12 includes LEDs 17, a light guide plate 16, a chassis 14, and a light source mounting member 30. The light guide plate 16 included a front surface configured as a light exit surface 16a, a rear surface configured as an opposite surface 16c, and two side surfaces configured as light entrance surface 16b. The light guide plate 16 is arranged such that the light entrance surface 16b are opposite light emitting surfaces 17a of the LEDs 17 and configured to guide light from the LEDs 17 toward the light exit surface 16a. The chassis 14 includes a plate-like portion 14a arranged on an opposite surface 16c side of the light guide plate 16. The light source mounting member 30 on which the LEDs 17 are mounted includes at least one bottom plate 30a including a front surface and a rear surface. The front surface is in surface-contact with a rear surface of the plate-like portion 14a. At least one portion of the rear plate surface is exposed to an external side.
