Abstract: A backlight unit includes a plurality of light source groups each including a plurality of light source units which generate light. The backlight unit further includes a light source substrate on which the light source groups are disposed and a plurality of light source drivers connected to the light source substrate to drive the light source groups. The light source substrate includes a first extension portion extended in a first direction. The light source units are disposed on the first extension portion. The light source substrate further includes a plurality of second extension portions extended from the first extension portion in a second direction crossing the first direction and a plurality of third extension portions extended from ends of the second extension portions in the first direction. The light source drivers are connected to the third extension portions to drive the light source groups.
