Patent ID: 8896767

Claim:
An illumination device, comprising: a light source; a light source substrate on which the light source is mounted; a reflective member that reflects light from the light source, and that has a light source insertion hole for inserting the light source, the reflective member covering a mounting surface on the light source substrate for mounting the light source; a first light-reflecting layer that reflects light from the light source, the first light-reflecting layer being formed at least in the light source insertion hole of the reflective member on the light source substrate; and a second light-reflecting layer disposed in the light source insertion hole of the reflective member on the light source substrate, the second light-reflecting layer having a light reflectance different from that of the first light-reflecting layer and being disposed so as to cover a portion of the first light-reflecting layer, wherein the second light-reflecting layer has a light reflectance lower than that of the first light-reflecting layer, and wherein the second light-reflecting layer is formed such that a proportion of area per unit area taken up by the second light-reflecting layer on the mounting surface of the light source substrate is smaller, the further away the second light-reflecting layer is from the light source.
