a second receiving unit including a bottom portion and a side portion being protruded from the bottom portion, the second receiving unit receiving the plurality of point light sources,
wherein the reflective sheet includes a portion disposed between the light guide plate and the bottom portion of the second receiving unit.
13. The backlight assembly of claim 12 , wherein the side portion faces the side wall.
14. The backlight assembly of claim 13 , wherein the side portion faces an inner surface of the side wall.
15. The backlight assembly of claim 13 , wherein the point light sources are disposed on the side portion.
16. The backlight assembly of claim 12 , wherein the bottom portion and the side portion comprise a metallic layer.
17. The backlight assembly of claim 16 , wherein the second receiving unit further comprises a line portion to apply a driving voltage to the point light sources.
18. The backlight assembly of claim 17 , wherein the second receiving unit further comprises an insulating layer formed between the metallic layer and the line portion.
19. The backlight assembly of claim 12 , wherein the second receiving unit is coupled to the first receiving unit.
20. A display apparatus comprising:
a light guide plate;
a plurality of point light sources facing a side surface of the light guide plate;
a reflective sheet disposed below the light guide plate;
a first receiving unit including a bottom plate and a side wall extended from the bottom plate, the first receiving unit receiving the light guide plate and the reflective sheet;
a second receiving unit including a bottom portion and a side portion being protruded from the bottom portion, the second receiving unit receiving the plurality of point light sources;
