The optical sheets include a plurality of sheet units. A storage unit for storing the flanges of the optical sheets has a sub-storage unit for storing the flanges of some sheet units. The flange of the other sheet unit excluded from the aforementioned some sheet units is larger than the sub-storage unit.

Abstract: Provided are an illumination device and a display device capable of even illumination. A positioning recess provided in a light guide plate and a peripheral portion of the recess are covered by a cover from one surface side of the light guide plate. As a result, the cover suppresses the emission of light emitted from the vicinity of the recess on the one surface of the light guide plate onto the outside of a backlight unit that functions as an illumination device. Thus, even if light is scattered at the recess of the light guide plate and the brightness of the vicinity of the recess is greater than the brightness of other portions, the leaking of excessively bright light onto the outside of the backlight unit (in this case, onto the display panel side) is suppressed. That is, brightness unevenness caused by the recess of the light guide plate is suppressed.
