Zusammenfassung:	The present invention relates to a backlight unit and a display device comprising the same. The backlight unit comprises: at least one light source unit including a plurality of light sources and a printed circuit board having the light source mounted thereon; a glass light guide plate including a light incident surface and a light emission surface wherein a light, emitted from the light source unit, is incident to the light incident surface and the light is emitted from the light emission surface; a reflection member arranged in a lower portion of the glass light guide plate to reflect light emitted toward a lower portion of the glass light guide plate; and a light conversion unit including a quantum dot which converts a wavelength of the light emitted from the light source unit. At least one surface of the light conversion unit is protected by the glass light guide plate. 본 발명은, 다수의 광원 및 상기 광원들이 실장된 인쇄회로기판을 포함하는 적어도 하나 이상의 광원 유닛과, 상기 광원 유닛으로부터 출사되는 광이 입사하는 입광면 및 광이 출사되는 출광면을 포함하는 유리 도광판, 상기 유리 도광판의 하부에 배치되어 유리 도광판의 하부로 출사되는 광을 반사시키는 반사 부재, 및 상기 광원 유닛으로부터 출사된 광의 파장을 변환시키는 양자점을 포함하는 광 변환부를 포함하며, 상기 유리 도광판에 의해 상기 광 변환부의 적어도 일면 이상이 보호되는 백라이트 유닛 및 이를 포함하는 표시장치에 관한 것이다.
