<p>A lighting apparatus (1, 2) of the present invention is provided with: a light source device having one or more light emitting diodes (143); a substrate (144) that is provided with the light source device; a light guide plate (141), which has a light input surface (141b) to which light outputted from a light output surface of the light source device is inputted, said light input surface being disposed to face the light output surface of the light source device, and a light emitting surface (141c) that emits the light inputted from the light input surface, and which propagates the light inputted from the light input surface, and outputs the light from the light emitting surface; and an engaging member (145, 845, 945), which is fixed to the substrate, engages the substrate with the light guide plate, and regulates mutual relative movement of the substrate and a light guide plate engaging area (146, 246) with the substrate, said mutual relative movement being in the direction in which the light output surface of the light source device and the light input surface of the light guide plate face each other.</p> |
