Abstract:
1. An edge light for illuminating a panel, comprising: a substrate; a light emitting element mounted on the substrate; terminal electrodes provided on a surface of the substrate and connected to the light emitting element for applying a current to the light emitting element; a convex seal made of a transparent material and sealing the light emitting element; wherein, each of the substrate and the convex seal has a rectangular shape in plan view; the convex shape of the seal has a first top in a direction of a long side of the rectangular shape of the substrate, and has a second top in a direction of a short side of the rectangular shape of the substrate; the first top has a first curved sectional shape; the second top as a second sectional shape; and a curvature of the first curved sectional shape is set to a value so that light beams discharged from the first top are expanded from both end faces of a long side of the substrate, thereby radiating a beam of light of an inverted trapezoid in a sectional view having a long side longer than the long side of the rectangular shape of the substrate.
