A backlight device includes an LED; a light guide plate that has a light-exiting surface provided at one plate surface, an opposite surface provided at a plate surface on the opposite side to the light-exiting surface, and a light-receiving side face provided at one side face, that is arranged such that the light-receiving side face faces the LED and that guides light from the LED; a chassis having a plate surface arranged so as to face the opposite surface and housing at least the LED and the light guide plate; and an optical sheet that is arranged so as to face the light-exiting surface, that provides light that has exited the light guide plate with an optical function and that has a bent portion that extends further toward the outside than an edge of the light-exiting surface and is bent toward the opposite surface side and as a result covers at least part of a side face of the light guide plate.
