DISPLAY DEVICE

To provide a display device with a high illuminance.SOLUTION: The display device according to an embodiment of the present specification includes: a substrate including a first sub-pixel to a third sub-pixel; a first electrode for each of the first sub-pixel to the third sub-pixel; a first light emission unit on the first electrode, the first light-emitting unit including a first light emission layer; a second light emission unit on the first light emission unit, the second light emission unit including a second light emission layer; a third light emission unit on the second light emission unit, the third light emission unit including a third light emission layer; and a second electrode on the third light emission unit. The first to third light emission layers emit different colors and the first electrode and the second electrode can be separate from each other by 310nm to 450nm.SELECTED DRAWING: Figure 1 【課題】高輝度を有する表示装置を提供すること。【解決手段】本明細書の実施例に係る表示装置は、第１～第３サブ画素を含む基板、第１～第３サブ画素のそれぞれにある第１電極、第１電極の上にあって第１発光層を含む第１発光部、第１発光部の上にあって第２発光層を含む第２発光部、第２発光部の上にあって第３発光層を含む第３発光部、および第３発光部の上にある第２電極を含み、第１～第３発光層が互いに異なる色を発光し、第１電極と第２電極の間の距離は、３１０ｎｍ～４５０ｎｍであり得る。【選択図】図１
