The reflective sheet is attached to the back surface board, has insertion holes in which the respective light emission sources are inserted, and reflects light emitted from the light emission sources. The back surface board has a plurality of projections that make portions of the reflective sheet bulge out toward the display panel in a state where the reflective sheet is attached.
