摘要： A display device includes a display panel unit and a backlight unit which radiates light toward the display panel. The display panel unit includes a display panel on an upper surface of a box-shaped panel housing which has first projecting portions on side walls of the housing. The backlight unit incorporates a light source in a bottom portion of a box-shaped light source housing which has second projecting portions on side walls of the light source housing. By bringing the first projecting portions and second projecting portions into contact with each other, a distance between the light source of the backlight unit and the display panel can be held. Further, by forming third projecting portions which project further than the first projecting portions on the panel housing, handling of the display panel unit is facilitated.
