A display device comprises: an optical member; a display panel disposed above the optical member; and a plurality of light emitting units disposed below the optical member and providing a first color light to the optical member. The optical member may include: a glass substrate having an upper surface and a lower surface facing each other in a thickness direction and overlapping the plurality of light emitting units in a plan view; and a quantum dot layer disposed directly on the upper surface or the lower surface and converting the first color light into a second color light and a third color light. 표시장치는 광학부재, 상기 광학부재의 상측에 배치된 표시패널, 상기 광학부재의 하측에 배치되며 제1 색광을 상기 광학부재에 제공하는 복수개의 발광유닛들을 포함한다. 상기 광학부재는 두께 방향에서 마주하는 상면 및 하면을 포함하고, 평면 상에서 상기 복수개의 발광유닛들에 중첩하는 유리기판 및 상기 상면 또는 상기 하면 상에 직접 배치되고, 상기 제1 색광을 제2 색광과 제3 색광으로 변환하는 양자점층을 포함한다.
