Abstract: A backlight unit includes a light source generating light, a light guide plate guiding the light in an upper direction, and an optical member disposed on the light guide plate to condense the light provided from the light guide plate in the upper direction. A top surface of the light guide plate includes a plurality of circular areas and a peripheral area around the circular areas. Each of the circular areas includes a central circular area and a ring area surrounding the central circular area. The optical member includes a first insulating layer disposed on the light guide plate and spaced apart from the light guide plate by predetermined distances in the ring areas and the peripheral area to define a plurality of cavities, and a second insulating layer disposed on the first insulating layer.
