A backlight (illumination device; 2) of the present invention includes: multiple light sources (5); and multiple light guides (7, 17, . . . ) for causing surface emission of light from the light sources (5). Each of the light guides (7, 17, . . . ) includes: a light-emitting section (7b, 17b, . . . ) having a light-emitting surface (7a); and a light guide section (7c) for guiding, to the light-emitting section (7b, 17b, . . . ), light from the light sources (5), a light-emitting section (7b) of a first light guide (7) being provided above a light guide section (17c) of a second light guide (17) adjacent to the first light guide (7). A light amount adjusting section (11) for reducing the amount of light incident on it is provided between the light-emitting section (7b) of the first light guide (7) and the light-emitting section (17b) of the second light guide. This allows for production of an illumination device having further improved luminance uniformity.
