The metal frame includes a bottom portion having a bottom surface that faces a surface on an opposite side to the light exit surface, a side wall erected on an outer periphery of the bottom surface, and a projecting portion provided on the side wall so as to project toward the bottom surface side. The metal frame houses the light source, the light guide plate, and the wiring board. At least a part of the light source is disposed between the bottom portion and the projecting portion, and the wiring board is disposed between the light source and the bottom portion.
