1. A backlight assembly, comprising:
- light emitting diodes in patterns;
a reflective sheet having a plurality of through holes through which the light emitting diodes protrude; and
a sidewall dividing the patterns into a plurality of light emitting diode units each including at least three light emitting diodes which emit red, green and blue colored lights respectively, wherein the sidewall is disposed between the plurality of light emitting diode units to surround each of the divided light emitting diode units, and the sidewall includes an opaque reflective material,wherein the sidewall is disposed on the reflective sheet, and wherein each of the through holes corresponds to each of the light emitting diodes.
