Abstract:
1. An illumination apparatus comprising: a light guiding plate; a plurality of light-emitting elements disposed along a side-end surface of the light guiding plate that serves as a light-entry portion, each of the plurality of light-emitting elements has a light-emitting surface facing toward the side-end surface; a light source substrate that extends along a direction which the side-end surface extends, a first surface of the light source substrate on which the plurality of light-emitting elements are mounted, and a second surface which is another surface of the light source substrate that opposes the first surface; a substrate support portion which has a third surface that faces the second surface and a fourth surface that opposes the third surface; and a screw that tightens the light source substrate to the substrate support portion from the fourth surface without being exposed on the first surface of the light source substrate, wherein the light source substrate includes a first substrate that configures the second surface and a second substrate that configures the first surface; and a through-hole that passes through the first substrate but does not pass through the second substrate, the through-hole being formed in a location of the light source substrate where the screw is tightened down.
