Abstract:
A lighting device includes LEDs, a light guide plate, and a frame. The light guide plate includes a light guide plate hole portion passing through in a thickness direction, a light entering surface, and a light exiting surface. The frame surrounds the light guide plate. The frame includes an outer peripheral wall portion and an inner peripheral wall portion. The outer peripheral wall portion opposes an outer peripheral end face of the light guide plate. The inner peripheral wall portion inserted to the light guide plate hole portion opposes an inner peripheral end face of the light guide plate on an inner side of the light guide plate hole portion. The inner peripheral wall portion has a configuration in which the opposing surface has a lower light reflectivity than that of an opposing surface of the outer peripheral wall portion.

Claim (Index 1):
A lighting device comprising:\n a light source; a light guide plate configured by a plate shaped member including a hole portion passing through in a thickness direction, the light guide plate including a light entering surface which is constituted of an outer peripheral end face of the plate shaped member and to which light from the light source enters, and a light exiting surface which is constituted of one plate surface of the plate shaped member and through which light entered through the light entering surface exits; and a frame surrounding the light guide plate, the frame including an outer peripheral wall portion opposing the outer peripheral end face of the light guide plate, and an inner peripheral wall portion inserted to the hole portion and opposing an inner peripheral end face of the light guide plate on an inner side of the hole portion and in which a surface opposing the inner peripheral end face has a lower light reflectivity than that of a surface opposing the outer peripheral end face of the outer peripheral wall portion.
