BACKLIGHT UNIT, DISPLAY DEVICE HAVING THE SAME, AND METHOD OF MANUFACTURING THE SAME

摘要

A backlight unit that includes a light source driving substrate and first and second light source units connected to the light source driving substrate. The first light source unit includes first and second light sources respectively emitting a first light having a first color and a second light having a second color. The second light source unit may include third and fourth light sources respectively emitting a third light having the first color and a fourth light having the second color. The first light source unit emits a first white color light having a first white color coordinate by mixing the first light and the second light and the second light source unit emits a second white color light having a second white color coordinate by mixing the third light and the fourth light. The first and second white color coordinates belong to different white color coordinate areas.
