Abstract: According to one embodiment, a backlight device includes a case having a bottom plate, a light guide having an emission surface, a second main surface and an incidence surface and arranged on the bottom surface, and a light source unit including a wiring board and light-emitting elements on the wiring board. Each light-emitting element has a mounting surface, a first side surface opposed to the mounting surface, and a light-emitting surface between the mounting surface and the first side surface. Each light-emitting surface faces the incidence surface, and the first side surfaces are arranged parallel to the second main surface, and the light source unit is fixed to the light guide with a fixing tape attached over each first side surface and the second main surface.
