Provided is an illumination device such that LED damage is avoided even if the LEDs are positioned to be in close proximity to a lateral end face of a thermally expanding light guiding plate. An illumination device (4) comprises: a light guiding plate (12) further comprising a plate shape; a chassis (14) further comprising a box shape, the upper face whereof is open, and wherein the light guiding plate (12) is housed; and LED substrates (20) which are positioned standing upon the bottom plate (14a) of the chassis (14) such that mounting faces (20a) whereon LEDs (21) are mounted opposing lateral end faces (12a) of the light guiding plate (12). Lateral plates (14b) (substrate attachment plates (16a)), opposing the lateral end faces (12a) of the light guiding plate (12), are disposed standing upon the bottom plate (14a) of the chassis (14). The LED substrates (20) are attached to the lateral plates (14b) (the substrate attachment plates (16a)) with shock absorbing members (15) disposed therebetween, the shock absorbing members (15) positioned between rear faces (20b) which are on the opposite side of the LED substrates (20) from the mounting faces (20a) thereof, and faces on the inner sides of the lateral plates (14b) (the substrate attachment plates (16a)).
