  • Publication number: 20250344562
    Abstract: A display device is disclosed. The display device may include a light-emitting element that outputs source light and a light control layer on the light-emitting element, which transmits the source light or converts the wavelength of the source light. The light-emitting element may include a first electrode, a second electrode facing (e.g., opposite to) the first electrode, at least one green light-emitting structure between the first electrode and the second electrode, and at least one blue light-emitting structure between the first electrode and the second electrode. The light control layer may include a green light control part including a green quantum dot that converts the wavelength of light emitted from the light-emitting element and emits green light. The power conversion efficiency of the green light control part may be less than about 32%, thereby being able to exhibit or provide excellent or suitable light efficiency and relatively high luminance characteristics.
