Abstract:
A backlight unit includes LEDs, a light guide plate, and a hood-shaped reflection member. The LEDs are linearly arranged at intervals. The light guide plate includes a light entering end surface and a light exiting plate surface. The light entering end surface is at least a part of the peripheral end surfaces extending along an arrangement direction of the LEDs and opposed to light emitting surfaces of the LEDs. The hood-shaped reflection member surrounds inter-LED spaces between adjacent LEDs and includes an opening a light guide plate side. The hood-shaped reflection member includes at least a first reflection portion and a pair of second reflection portions. The first reflection portion is opposed to the light entering end surface  15 a.  The second reflection portions are separated from each other in a thickness direction of the light guide plate such that the inter-LED spaces LS are between the second reflection portions.

Claim (Index 1):
A lighting device comprising:\n a plurality of light sources linearly arranged at intervals; a light guide plate having a flat plate shape, the light guide plate including:\n a light entering end surface extending along an arrangement direction of the light sources, the light entering end surface being at least a part of a peripheral end surface of the light guide plate opposed to light emitting surfaces of the light sources; and \n a light exiting plate surface through which light rays exit, the light exiting plate surface being one of plate surfaces of the light guide plate; and \n a hood-shaped reflection member surrounding at least an inter-light source space between the adjacent light sources and including an opening on a light guide plate side, the hood-shaped reflection member including at least:\n a first reflection portion opposed to the light entering end surface; and \n a pair of second reflection portions continuous from the first reflection portion to be separated from each other in a thickness direction of the light guide plate such that the inter-light source space is between the second reflection portions.
