1. A backlight assembly comprising:
- a circuit board; and
a plurality of point light source groups arranged on the circuit board in a matrix shape having a plurality of rows and a plurality of columns, each of the point light source groups having red, green, blue and white point light sources arranged in a substantially squared form,wherein a first point light source group is adjacently disposed at a left side of a second point light source group, and a third point light source group is adjacently disposed at a right side of the second point light source group,wherein the first point light source group, the second point light source group and the third point light source group are arranged in the same row,wherein positions of the red, green, blue and white point light sources of the second point light source group are rotated by an angle of about 90 degrees in a clockwise direction with respect to positions of the red, green, blue and white point light sources of the first point light source group, and positions of the red, green, blue and white point light sources of the third point light source group are rotated by an angle of about 90 degrees in a clockwise direction with respect to the positions of the red, green, blue and white point light sources of the second point light source group.

Abstract
A backlight assembly includes a circuit board and a plurality of point light source groups. The plurality of point light source groups includes N point light sources that generate different respective colors and being arranged on the circuit board. Here, N is a number of point light sources. One light source group of the light source groups is rotated by an angle of predetermined degrees in a clockwise direction or a counter-clockwise direction with respect to another light source group that is adjacent to the one point light source group.
