Abstract: A display device includes a display layer to emit source light, and a light control layer disposed on the display layer to either transmit the source light or wavelength-convert the source light, wherein the light control layer may include a blue light control portion to emit blue light, a green light control portion to emit green light, and a red light control portion to emit red light, and the green light control portion may include multiple first quantum dots and multiple modified scatterers, and the modified scatterers may each include a core portion whose length in a long side direction of the modified scatterer may be 1.5 times or greater than a length in a short side direction of the modified scatterer, and a metal coating portion surrounding at least one of an upper portion and a lower portion of the core portion.
