Zusammenfassung:	To provide a display device that has a wide color band, a high contrast ratio, and high luminance.SOLUTION: A display device includes: an optical member, a display panel arranged above the optical member; a plurality of light-emitting units arranged below the optical member and providing first color light to the optical member; and a protective member accommodating the plurality of light-emitting units, the optical member, and the display panel. The optical member includes a glass substrate including an upper surface and a lower surface that face each other in a thickness direction and superposed on the plurality of light-emitting units in a plan view, and a quantum dot layer arranged directly on the upper surface or the lower surface and converting the first color light into second color light and third color light.SELECTED DRAWING: Figure 2D 【課題】広い色帯域、高い明暗比、及び高輝度を有する表示装置を提供する。【解決手段】本発明による表示装置は、光学部材と、前記光学部材の上側に配置される表示パネルと、前記光学部材の下側に配置され、第１色光を前記光学部材に提供する複数の発光ユニットと、前記複数の発光ユニット、前記光学部材、及び前記表示パネルを収容する保護部材と、を有し、前記光学部材は、厚さ方向で向い合う上面及び下面を含み、平面視において前記複数の発光ユニットに重畳するガラス基板と、前記上面又は前記下面の上に直接配置され、前記第１色光を第２色光と第３色光に変換する量子点層と、を含む。【選択図】図２Ｄ
