Abstract: Provided is a back-light unit. The back-light unit includes: a reflective layer; a light transmitting plate including a plurality of light emitting diodes; and an optical member disposed on the light transmitting plate and separated from the light transmitting plate with an air layer therebetween, in which light generated from the light emitting diode is reflected to the reflective layer and then passes through the light transmitting plate to reach the optical member.
