Abstract
According to one embodiment, an illumination apparatus includes an LED (Light Emitting Diode) module, a light guide plate, and a support body. The support body supports the LED module and the light guide plate. A reflective surface of the support body is provided between a portion supporting the LED module and a portion supporting the light guide plate. The reflective surface is reflective with respect to the light emitted from the LED package. The LED module is tilted relative to the reflective surface with the LED package mounting surface being toward the reflective surface. An angle between the LED module and the reflective surface is less than 90°.
