Claim:
1. A backlight assembly comprising: a plurality of first light sources configured to emit a first color; and a plurality of second light sources configured to emit a second color different from the first color, wherein the backlight assembly is divided into a first boundary area, a second boundary area spaced apart from the first boundary area in a first direction, and a middle area between the first boundary area and the second boundary area, wherein an arrangement direction of a first set of first and second light sources of the plurality of first and second light sources disposed on a same substrate in each of the first and second boundary areas is different from an arrangement direction of a second set of first and second light sources of the plurality of first and second light sources in the middle area, and wherein each of the plurality of the first light sources includes two contiguous first light sources defining an arrangement direction of the two contiguous first light sources, the two contiguous first light sources both emit the first color, and each of the plurality of the second light sources includes two contiguous second light sources defining an arrangement direction of the two contiguous second light sources, the two contiguous second light sources both emit the second color, wherein the backlight assembly further comprises: a first substrate which extends in a second direction which is substantially perpendicular to the first direction, and has a width in a third direction which is substantially perpendicular to the first and second directions; and a light guiding plate adjacent to the first substrate; wherein first and second light sources of the plurality of first and second light sources are disposed on the first substrate, wherein the light guiding plate has a light incident surface and a light exiting surface connected to the light incident surface, the light incident surface and the light exiting surface are substantially perpendicular to each other, the light incident surface faces the first and second light sources.
